-4 (5y + 5) = -120
multiply the bracket by -4
(-4)(5y)=-20y
(-4)(5)=-20
-20y-20=-120
move -20 to +20
-20y-20+20=-120+20
-20y=-120+20
-20y=-100
divide both sides by -20 to get y by itself
-20y/-20=-100/-20
Answer: y=5
We have been given two functions 
and 
. We are asked to find 
.
We will use composite function property 
to solve our given problem.
Now we will combine like terms as:
Therefore, the value of would be 
.
