(x-3)^2=(3x+10)*(x-3) so to solve this u can simply take (x-3) over to the other side so it will; look like this
(x-3)^2/(x-3)=3x+10
then it will be x-3=3x+10
-2x=13
x=-13/2 which is -6.5
Equation 1) y = x² + 10x + 11
Equation 2) y = x² + x - 7
Subtract equations from one another.
9x = 18
Divide both sides by 9.
x = 2
Plug in 2 for x in the first equation.
y = x² + 10x + 11
y = 2² + 10(2) + 11
Simplify.
y = 4 + 20 + 11
y = 35
Plug in 35 for y and 2 for x in the first equation to check your work.
y = x² + 10x + 11
35 = 2² + 10(2) + 11
35 = 4 + 20 + 11
35 = 24 + 11
35 = 35
So, we know that our answer is correct! :))
x = 2, y = 35
Answer:
y=3x-16
Step-by-step explanation:
The answer is 150 parents. Because 450/3=150
