Answer:
x = 7
y = 8
Step-by-step explanation:
4y-4 = 28
4y = 32
y = 8
10x+65 = 135
10x = 70
x = 7
For this case we have the following functions:
We must find 
By definition of composition of functions we have:
So:
![(p-9) (x) = x ^ 2-1- [5 (x-1)] = (x ^ 2-1) -5 (x-1)](https://tex.z-dn.net/?f=%28p-9%29%20%28x%29%20%3D%20x%20%5E%202-1-%20%5B5%20%28x-1%29%5D%20%3D%20%28x%20%5E%202-1%29%20-5%20%28x-1%29)
Thus, the correct option is option C.

Answer:
x = 27/5
Step-by-step explanation:
Step 1: Write equation
-12 = -5(x - 3)
Step 2: Solve for <em>x</em>
- Distribute -5: -12 = -5x + 15
- Subtract 15 on both sides: -27 = -5x
- Divide both sides by -5: x = 27/5
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
-12 = -5(27/5 - 3)
-12 = -5(12/5)
-12 = -12
