Answer:
y - 4
Step-by-step explanation:
subtract 12 from both sides of the equation
4y+12-12= -7y +24 - 12
-4y = -7y +24 - 12
subtract
-4y +-7y + 12
add 7y to both sides of the equation
-4y + 7y = -7y +12 + 7y
simplify
3y + -7y +12 + 7y
combine like terms.
3y = 12
divide
3y/3
=12/3
simplify
y=12 3
y = 4
Answer:
y = 4
Step-by-step explanation:
Given the algebraic equation, -4y + 12 = -7y + 24, the goal is to solve for the value of y by isolating it to either sides of the equation.
Start by adding 7y to both sides of the equation:
-4y + 7y + 12 = -7y + 7y + 24
3y + 12 = 0 + 24
3y + 12 = 24
Next, subtract 12 from both sides:
3y + 12 - 12 = 24 - 12
3y = 12
Divide both sides by 3 to isolate and solve for y:
[tex]\frac{3y}{3} = \frac{12}{3}[/tex]
y = 4
Double-check whether the value of y will provide a true statement if plugged into the equation:
-4y + 12 = -7y + 24
-4(4) + 12 = -7(4) + 24
-16 + 12 = -28 + 24
-4 = -4 (True statement).
Therefore, the value of y = 4.
There was a sample of 350 milligrams of a radioactive substance to start a study. since then, the sample has decayed by 7.3% each year. let t be the number of years since the start of the study. let y be the mass of the sample in milligrams. write an exponential function showing the relationship between y and t .
Answer:
y = 350*0.927^tStep-by-step explanation:
Initial amount = 350 mgDecay = 7.3% per year or 0.073Time = t yearsFinal mass = yThe equation:
y = 350*(1 - 0.073)^t = 350*0.927^tEvaluate the question

Answer:
B) y = 5x + 29
Step-by-step explanation:
A parallel line means it will have the same slope.
So far our equation looks like this: y = 5x + b
We will now plug in (-6, -1) to solve for b.
y = 5x + b
(-1) = 5(-6) + b
-1 = -30 + b
29 = b
So our answer is y = 5x + 29
This is option B

Answer:
f(x) = x³ -4x² -5x +20
Step-by-step explanation:
If the function is to have rational coefficients, each complex or irrational square root must have a matching conjugate. That is, both -√5 and +√5 must be roots. If there is a root p, then there is a factor (x -p). The factored form of the minimal polynomial is ...
f(x) = (x -4)(x +√5)(x -√5)
= (x -4)(x² -5)
f(x) = x³ -4x² -5x +20

Step-by-step explanation:
a midsegment is the line segment connecting the midpoints of two sides of a triangle. Since a triangle has three sides, each triangle has three midsegments (that create the midsegment triangle). A triangle midsegment is parallel to the third side of the triangle and is half of the length of the third side (due to similar triangles and their constant scaling factors, when one side of the similar triangle is half of the sys of the original triangle, then all its sides are half of their original counterparts).
the 3 sides of the main triangle are
2x + 5
3x - 1
5x
the perimeter of the main triangle is the sum of these :
2x + 5 + 3x - 1 + 5x = 10x + 4
since the sides of the midsegment triangle are all exactly half the length of the sides of the main triangle, also the perimeter of the midsegment triangle is half of the perimeter of the original triangle :
(10x + 4) / 2 = 5x + 2

I built a toy model of my car that is 15 inches long.If my actual car is 20 feet long.What is the scale distance between the toy model and the actual car?
If I built a toy model of my car for the given condition the scale distance between the toy model and the actual car will be 225 inches.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
The term PEMDAS describes the sequence in which arithmetic operations must be carried out in an equation.
It is given that the length of the toy model car is 15 inches and the actual car is 20 feet
As we know 1 foot consists of 12 inches as a result 20 feet has 240 inches.
The scale distance between the toy model and the actual car is the difference between the actual length and the model length.
Scale distance = 240 inches - 15 inches
Scale distance =225 inches
Thus, if I built a toy model of my car for the given condition the scale distance between the toy model and the actual car will be 225 inches.

Mr. Ryan is buying a home for $250,000. He is making a 20% down payment and
financing the rest with a 25-year loan at 5% interest. What will his monthly payment
be?
Since 20% down payment, we will find the 20% of that $250,000.
10% is $25,000, now times by 2 would be 20% which is $50,000.
Now $250,000 - $50,000 = $200,000 which would be rest of the non-payed payment.
We will divide $200,000 with the 25 year loan. $200,000/25 = $8,000
There is also the 5% interest.
1% of $8,000 is $80 and times that by 5 would be 5% which is $400.
$8,000 + $400 = $8,400.
Since it is monthly, we will divide $8,400 by 12 months. $8,400/12 = $700.
The monthly payment would be $700.
(I hope this is correct.)

34.98+12.24=?
answers please
Answer:
Hello!
After reading your question I have calculated the correct answer to be:
47.22
Step-by-step explanation:
The way I solved this equation was I first split the equation into two parts.
I took the two whole numbers, being "34" and "12", and made their own equation:
"34+12=?"
And then I took the two partial numbers "0.98" and "0.24" and made their own equation:
"0.98+0.24=?"
I then solved both equations:
"34+12= 46"
"0.98+0.24= 1.22"
And added those two solutions together to come up with the final solution:
"46+1.22= 47.22"
Hope this helped!
Answer:
47.22 is the answer
