What number makes the equation true? Enter the answer in the box.
= 2 = 8
= 8
Answer:
a = 4
Step-by-step explanation:
Let the number be a.
2× a = 8 ...(1)
We need to find the value of a such that th above equation is true.
Divide both sides of equation (1) by 2 .
a = 8/2
a = 4
Hence, if the value of a is 4 the equation will become true.

what is the range of this function and pls explain
Answer:
[tex]f(x)\geq -2[/tex]
Step-by-step explanation:
Range corresponds to the values of y on the y-axis. If we see the graph the minimum value of the y-coordinate is -2 and then it tends to increase from it. We do not know till where the y values will increase in the figure it shows 6 but it's still actually increasing we keep on tracing the graph but the minimum value will always remain the same which is -2 . So we can say that the range of the function is
[tex]f(x)\geq -2\\[/tex]
Where f(x) is the function and since the values of y on the y-axis increase from -2 we can say that the function has the range of values greater than or equal to -2
Alexia spent 3 minutes working on each of her math problems and 4 minutes on each of her science problems. Her homework took her more than 60 minutes to complete. The boundary line for the inequality 3x + 4y > 60 is shown.
Answer:
The correct answer to this problem is the third statement which is "Alexia completed 20 math problems and 10 science problem". The following conditions are stated in the problem:
Alexia can answer 3 minutes on each math problem
Alexia can answer 4 minutes on each science problem
She worked more than 60 minutes
We have the inequality 3x + 4y > 60 where x represents the total number of math problem while y represents the total number of the science problem.
in our answer, we have x=20and y=10
3*20 + 4*10 > 60
60 + 40 > 60
100 > 60

help!! offering lots of points and brainliest!
Answer:
It would be C
Step-by-step explanation:
So, shows in the graph, you can see that the change in rise is 100, because to get to 150 from 50, you add 100
And the run is 1, because to go from 0 to 1, you add 1
Meaning the slope is 100/1

Answer:
x=7
Step-by-step explanation:
Answer:
x = 7
Step-by-step explanation:
Equating the expression for area to the given area
2x² - 7x - 4 = 45 ( subtract 45 from both sides )
2x² - 7x - 49 = 0 ← in standard form
To factor consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term
product = 2 × - 49 = - 98 and sum = - 7
The factors are - 14 and + 7
Use these factors to split the middle term
2x² - 14x + 7x - 49 = 0 ( factor the first/second and third/fourth terms )
2x(x - 7) + 7(x - 7) = 0 ← factor out (x - 7)
(x - 7)(2x + 7) = 0
equate each factor to zero and solve for x
x - 7 = 0 ⇒ x = 7
2x + 7 = 0 ⇒ 2x = - 7 ⇒ x = -
Thus the positive value for x is x = 7

Identify an equation in point-slope form for the line parallel to y+-2/3x+8 that passes through (4, -5).
Step-by-step explanation:
Line parallel to the line y = -2/3 x + 8 also has the slope -2/3.
Since the line passes through (4, -5), we have (x - 4) written on the right side and (y + 5) on the left side.
Hence the equation is y + 5 = -2/3 * (x - 4). (B)
Una casa de dos plantas esta construida en un terreno rectangular de 66m² , tal como lo muestra los siguientes pasos si x es el frente de la casa y x+5 el largo. De la ecuacion cuadratica que define el area del terreno es x² + 5x-66=0 ¿Cuanto mide el frente de la casa?
Answer:
El frente de la casa es 6 metros.
Step-by-step explanation:
El area de la casa está dada por el área de un rectángulo:
[tex]A = f*l = x (x+5) = 66[/tex]
En donde f es el frente = x , l es el largo = x+5 y A es el área = 66m²
Si la ecuación cuadrática que define el área del terreno viene dado por:
[tex] x^{2} + 5x - 66 = 0 [/tex]
Resolviendo la ecuación cuadrática para x tenemos:
x₁ = -11 y x₂ = 6
Tomando el valor positivo, podemos decir que el frente de la casa es 6 metros.

I need the measure of angle 1
Answer:
Angle 1 is 69°
Step-by-step explanation:
9x + 66 = -9x + 156
9x + 9x = 156 - 66
18x = 90
18x/18 = 90/18
x = 5
-9x + 156
-9(5) + 156
-45 + 156
111
180 - 111 = 69.
Write the slope-intercept form of the equation that is described below.
Through (-3, 3) and parallel to y = 1/3x + 5
Final Answer: [tex]y = \frac{1}{3}x + 4[/tex]
Steps/Reasons/Explanation:
There are two methods of solving this problem. Slope-intercept form and Point-slope form. I will be using the Slope-intercept form to solve this problem.
Step 1: Substitute slope from the original line ([tex]\frac{1}{3}[/tex] in this case) into the slope-intercept equation.
[tex]y = \frac{1}{3}x + b[/tex]
Step 2: Substitute the given point [tex](-3, 3)[/tex] into the x and y values.
[tex]y = \frac{1}{3}x + b[/tex]
[tex]3 = \frac{1}{3}(-3) + b[/tex]
Step 3: Solve for b (the y-intercept).
[tex]3 = \frac{1}{3}(-3) + b[/tex]
[tex]3 = -1 + b[/tex]
[tex]+1[/tex] = [tex]+1[/tex] [tex]+[/tex] [tex]b[/tex]
[tex]4 = b[/tex]
Step 4: Substitute this value for b in the slope-intercept form equation.
[tex]y = \frac{1}{3}x + 4[/tex]
~I hope I helped you :)~
Answer:
y = 1/3x + 5
Step-by-step explanation:
(-3, 3)
x , y
x1 = -3
y1 = 3
The formula we will use is y - y1 = m ( x - x1)
We will now replace y1 and x1 with the coordinate points (-3, 3).
We will keep x1 = -3, and y1 = 3.
then you will plug in the numbers giving you an equation like:
y - (3) = 1/3 (x -(-3))
y - 3 = 1/3 (x + 3)
y - 3 = 1/3x +1
+ 3 + 3
y = 1/3x + 4
I am 100% sure I am correct.

The following chart shows the number of rows in an auditorium and the total number of seats. What equation defines the number of seats with respect to the number of rows.
a) S=20R+100
b) S=40R+120
c) S=20R+60
d)S=20R
Answer:
Answer: c) S=20R+60
Step-by-step explanation:
Linear Model
The chart supplied shows the number of rows (R) in an auditorium and the total of seats (S).
We'll find the equation that relates them. The equation of a line can be expressed in the slope-intercept form:
S = mR + b
Where m is the slope and b is the intercept.
The slope is found by:
[tex]\displaystyle m=\frac{S_2-S_1}{R_2-R_1}[/tex]
We'll use two sample points (20,460) and (45,960):
[tex]\displaystyle m=\frac{960-460}{45-20}=\frac{500}{25}[/tex]
m = 20
The value of b can be found by using one of the points, for example (20,460), and having m=20:
460 = 20*20 + b
Thus: b = 460 - 400 = 60.
The equation is:
S = 20R + 60
You can test the other points and check they belong to the same line.
Answer: c) S=20R+60

Answer:
C
Step-by-step explanation:
Have you ever wondered why runners start at different spots on a track instead of lining up together? This is called a staggered start. Since tracks have semicircles (or half circles) on the ends, if all the runners lined up together, runners in outer lanes would need to run farther than runners in inner lanes. Why? Because the circumference of the outer lane is greater than the circumference of the inner lane. Staggering starting positions ensures that all runners run the same distance! Where do you see circles and semicircles in the world around you? Why could finding the area or circumference be helpful?
Step-by-step explanation:
A. Where do you see circles and semicircles in the world around you?
1. Ring.
2. Earing
3. Coin
4. Hockey puck
5. Car tyre
6. Dartboard
7. Wreath
8. Plate
9. Hula hoop
10. Mercedes logo
11. Bass drum
12. Drain
B. Why could finding the area or circumference be helpful?
Finding the area or circumference can help us estimate the size of these circular shape/figures, it can tell us the amount of space they can occupy or the amount of materials needed to produce them

Which orchard would be cheaper to visit if the class has 12 students?
Orchard A) admission costs $9 per person and 3 chaperones are required.
Orchard B) the cost is $10 per person, but only 1 chaperone is required.
Answer: orchard B
Step-by-step explanation: (orchard A) if you were to only bring the 12 students, the cost would be $108. But since it requires 3 chaperones you’d add 3 to the already 12 students making the full cost $135.
(Orchard B) if you were take only the 12 kids to the orchard it would cost you $120 but because it requires ONLY 1 chaperone, the final cost would be $130. allowing it to be $5 dollars less than what Orchard A would cost.
