It should be noted that the value on the blank on the equation will be -2.
How to solve the equationThe equation given is:
2(4x+1) + 8 = 4(2x+1) + 8 - x
Simplifying the left-hand side:
8x + 2 + 8 = 8x + 4 + 8 - x
Simplifying the right-hand side:
8x + 4 + 8 - _ = 8x + 12 - x
Combining like terms on both sides:
8x + 10 = 8x + 12 - x
Subtracting 8x from both sides:
10 = 12 - x
x = 10 - 12
x = -2

what is the acceleration of a bus whose speed changes from 126 m/s to 306 m/s over a period of 3seconds
Answer: The acceleration of the bus can be calculated using the formula:
a = (v2 - v1) / t
where:
a = acceleration
v2 = final velocity = 306 m/s
v1 = initial velocity = 126 m/s
t = time = 3 seconds
Substituting the given values into the formula, we get:
a = (306 m/s - 126 m/s) / 3 s
a = 180 m/s / 3 s
a = 60 m/s^2
Therefore, the acceleration of the bus is 60 m/s^2.
Step-by-step explanation:
Luke’s parents started a savings account to help him pay for college or a technology school when he turned 11 years old. Each month they put $125 into the savings account, and they continued this until he was 18 years old. The savings account did not accumulate any interest. Luke figured out that the first year of a technology school that he wanted to attend would cost him $12,480. If he had one year to save the rest of the money, how much would he need to save each month?
A. 165
B.40
C.1980
D.1040
B has a savings account, into which he must deposit $40 each month.
What's the point of the example?Interest is frequently calculated as an annual percentage of the amount borrowed. This percentage represents the loan's interest rate. For instance, a bank will pay interest if you deposit money in a high-yield savings account.
From the time he was 11 to the time he was 18, Luke's parents saved for him for 8 years, or 8 years x 12 months every year, or 96 months.
Since they were saving $125 per month throughout this time, Luke had amassed the following sum:
$125/month x 96 months = $12,000
Luke must still pay the following expenses because he needs $12,480 for his first year of technological school:
$12,480 - $12,000 = $480
If he has one year left to save this amount, he will need to save:
$480÷12months = $40per month
Therefore, the answer is B. $40.

A=(a, e, i, o, u),B=(a, b, c) and C=(a, c, e, g)
B intersaction C= C intersaction B
The given statement "B ∩ C = C ∩ B" is true, since the intersection of two sets is a commutative operation, which means the order in which we list the sets does not matter.
To find the intersection of two sets, we need to identify the elements that are common to both sets. In this case, we can list the elements of each set and identify their common elements:
B = {a, b, c}
C = {a, c, e, g}
B ∩ C = {a, c}
C ∩ B = {a, c}
As we can see, the intersection of B and C is {a, c}, and the intersection of C and B is also {a, c}. The order in which we list the sets does not affect the result of the intersection operation, since the elements of both sets are the same.
Therefore, we can conclude that B ∩ C = C ∩ B is true, and that the intersection of B and C contains the same elements regardless of the order in which we list the sets.
In summary, the intersection of two sets is a commutative operation, which means that the order in which we list the sets does not affect the result. Therefore, B ∩ C = C ∩ B is true, and the intersection of B and C contains the same elements regardless of the order in which we list the sets.

A toy company is building dollhouse furniture. A rectangle door of a dollhouse has a height of 7 centimeters and a width of 3 centimeters. What is the perimeter of the door of a scale drawing that uses a scale factor of 3. 5?
If a rectangle door of a dollhouse has a height of 7 centimeters and a width of 3 centimeters, the perimeter of the door in the scale drawing is 70 centimeters.
To find the perimeter of the door in the scale drawing, we first need to determine the dimensions of the door in the scale drawing. To do this, we need to multiply the actual dimensions of the door by the scale factor of 3.5.
The height of the door in the scale drawing would be 7 cm x 3.5 = 24.5 cm, and the width would be 3 cm x 3.5 = 10.5 cm.
The perimeter of the door in the scale drawing can be calculated by adding up the lengths of all four sides. The two vertical sides have a length of 24.5 cm, and the two horizontal sides have a length of 10.5 cm. Therefore, the perimeter of the door in the scale drawing is:
P = 2(24.5 cm) + 2(10.5 cm) = 49 cm + 21 cm = 70 cm
Note that the scale drawing is a proportional representation of the actual door, where all corresponding dimensions are multiplied by the same factor of 3.5.

the perpendicular, Based on these measurements, fiad the length of the entire tunnel,
Do not round any intermediate computations. Round your answer to the nearest tenth..
Note that the figure below is not drawn to scale.
Answer: Approximately 2 * AC = 737.2 meters. Rounded to the nearest tenth, the answer is 737.2 meters.

where A and B are the entrances of the tunnel, C is the point in the middle of the tunnel that we want to find, and θ, x, and y are the angles and distances given in the problem. We want to find the length of AC.
Using trigonometry, we can find the distances BC and AB: tan(57°) = x / y => x = y * tan(57°)
tan(14°) = x / (y + 212) => x = (y + 212) * tan(14°)
Setting these two expressions for x equal, we get: y * tan(57°) = (y + 212) * tan(14°)
Solving for y, we get: y = 212 / (tan(57°) / tan(14°) - 1) ≈ 286.5 meters
Now we can use the law of sines to find the length of AC: sin(θ) / AC = sin(14°) / BC = sin(57°) / AB
Solving for AC, we get: AC = AB * sin(θ) / sin(57°) ≈ 368.6 meters
Therefore, the length of the entire tunnel is approximately 2 * AC = 737.2 meters. Rounded to the nearest tenth, the answer is 737.2 meters.

Find the median of first 15 odd numbers 
Answer:
15
Step-by-step explanation:
The first 15 odd numbers are: 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29
The formula to find the median of a set of numbers is:
Median = [(n + 1) / 2]th term
where n is the total number of terms in the set.
In this case, we have 15 terms in the set of the first 15 odd numbers. So, substituting n = 15 in the formula, we get:
Median = [(15 + 1) / 2]th term
Median = 8th term
To find the 8th term, we can simply list the first 15 odd numbers in ascending order and count 8 numbers from the beginning of the list. The 8th term is 15.
Therefore, using the formula, we get:
Median = 8th term = 15.
So, the median of the first 15 odd numbers is 15.

Length of the rectangle (L) = 4 * diameter of circle (we have 4 circles)
Length of the rectangle = 4 * 3 = 12 cm
Width of the rectangle (W) = diameter of circle = 3 cm
Area of rectangle = L * W
Area of rectangle = 12 * 3 = 36 cm²
Area of circle = πr²
Area of circle = π * 1.5² = 2.25π cm²
Area of the blue region = Area of rectangle - Area of circle
Area of the blue region = 36 - 2.25π
Area of the blue region = 36 - (2.25* 22/7)
Area of the blue region = 28.93 cm²

Determine the voltage dropped across
The answer of the given question based on the Voltage drop the answer is , the voltage dropped across R3 is 277.11 V.
What is Ohm's law?Ohm's law is fundamental principle in electrical engineering and physics that describes relationship between voltage, current, and resistance in electrical circuit. It states that current through conductor between two points is directly proportional to voltage across two points, and inversely proportional to resistance between them.
To determine the voltage dropped across R3, we need to use Ohm's law and Kirchhoff's circuit laws. First, we can calculate the total resistance in the circuit:
Rtotal = R1 + R2 || R3
R2 || R3 = (R2 * R3) / (R2 + R3) (parallel resistance formula)
Rtotal = R1 + (R2 || R3)
Rtotal = 152 + ((18 * 362) / (18 + 362))
Rtotal = 149.89 Ω (rounded to 2 decimal places)
Next, we can use Ohm's law to calculate the current flowing through the circuit:
I = ET / Rtotal
I = 120 / 149.89
I = 0.8004 A (rounded to 4 decimal places)
Finally, we can use Kirchhoff's voltage law to determine the voltage dropped across R3:
ET = IR1 + IR2 || IR3 + IR3
ET = I(R1 + R2 || R3) + IR3
ET - I(R1 + R2 || R3) = IR3
R3 = (ET - I(R1 + R2 || R3)) / I
R3 = (120 - (0.8004 * (152 + ((18 * 362) / (18 + 362))))) / 0.8004
R3 = 277.11 V (rounded to 2 decimal places)
Therefore, the voltage dropped across R3 is 277.11 V.

The statement that is true regarding the graphed functions is that: B. f(-2) = g(-2).
What is the point-slope form?Mathematically, the point-slope form of a straight line can be calculated by using this mathematical expression:
y - y₁ = m(x - x₁) or y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)
Where:
m represents the slope.x and y are the points.At point (2, 0), an equation of the line f(x) can be calculated by using the point-slope form:
y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)
y - 0 = (-4 - 0)/(-2 - 2)(x - 2)
y = -x + 2
For line g(x), we have:
y - 4 = (-2 - 4)/(0 + 2)(x + 2)
y = -3(x + 2) + 4
y = -3x - 2
When x = 0, we have:
g(0) = 0 + 2 = 2
f(0) = 0 - 2 = -2.
When x = -2, we have:
g(-2) = -(-2) + 2 = 4
f(-2) = -3(-2) - 2 = 4.

three linear funtions are represented below
help me please
Answer: B
Rate of change is the slope which is the [tex]\frac{rise}{run}[/tex]= [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
In the first equation, we will substitute x with any two random numbers to get the y value, which gives us two points. The number you take doesn't matter.
y=2, taking x as 2 so the point is (2,2)
y=1, taking x as 1 so the point is (1,1)
m=[tex]\frac{2-1}{2-1}=1[/tex] SO THE SLOPE FOR A IS 1
In the second equation, we can just pick 2 points on the graph that the line runs through. I picked (2,-1) and (0,-4) to make calculations easy
[tex]m=\frac{-4-(-1)}{0-2}\\ =\frac{-3}{2}\\[/tex]OR THE SLOPE IS -1.5
In the thrid equation, we can again just pick points to find the ROC.
[tex]m=\frac{9-6}{5-4} \\ =3[/tex]THE SLOPE IS 3
Now that we have found this out, we can now find out which one has a bigger ROC.

Given: ABCD pyramid All edges congruent AB = 4. 5 Find: V
The volume of the pyramid is found to be approximately 18.046 cubic units.
To find the volume (V) of the pyramid, we need to use the formula for the volume of a pyramid, which is V = (1/3) × Base Area × Height.
In this case, the base is a square, so we can find the area of the base by squaring one of the sides: Base Area = AB² = 4.5² = 20.25.
To find the height of the pyramid, we need to use the Pythagorean theorem to find the slant height, and then use that to find the height. Let h be the height of the pyramid and s be the slant height. We have:
s² = AB² + (1/2) DC² (Pythagorean theorem for triangle ABC)
s² = 4.5² + (1/2) DC²
Since all edges of the pyramid are congruent, we have DC = AB = 4.5. Substituting this into the equation above, we get:
s² = 4.5² + (1/2) × 4.5²
s² = 30.375
s ≈ 5.509
To find the height h, we can use the Pythagorean theorem again for triangle ABD:
h² = AB² - (1/4) s²
h² = 4.5² - (1/4) × 30.375
h² ≈ 7.875
h ≈ 2.807
Now that we have found the base area and the height, we can use the formula for the volume of a pyramid to find V:
V = (1/3) × Base Area × Height
V = (1/3) × 20.25 × 2.807
V ≈ 18.046
Therefore, the volume of the pyramid is approximately 18.046 cubic units.

the sidesof one of the pentagons are a, , 20,c and 30 respectively if the corresponding sides of hte other pentagon are 46, 50, d, 102 and 24 respectively. what are the mising measures
The missing measures of the pentagon are a = 18.4, c = 61.2, d = 75, and x = 22.08.
What are the missing measures of the pentagon?
Let's label the sides of the first pentagon as a, 20, c, 30, and x, and the sides of the second pentagon as 46, 50, d, 102, and 24.
Since both pentagons have the same shape, we know that the corresponding sides are proportional. This means we can set up the following equations:
a/46 = 20/50 = c/d = 30/102 = x/24
Solving for the missing variables:
a = 46(20)/50 = 18.4
c = 30(102)/50 = 61.2
d = 50(30)/20 = 75
x = 24(46)/50 = 22.08
Therefore, the missing measures are a = 18.4, c = 61.2, d = 75, and x = 22.08.
