a) (f+g)(x) = f(x) + g(x) = -4x + 5x = x

b) -9(x) = -9x? I have no idea what this means.

c) (f o g)(x) = (f(g(x)) = f(5x) = -4 (5x) = -20x

Describe two different ways to solve: -10=1/4(8y-12)
timurjin [86]
There are two ways to approach this question. The first is to divide both sides of the equation by 1/4, which is the same as multiplying by 4.
4*(-10)=4*(1/4)(8y-12)
-40=1(8y-12)
-40=8y-12
-40+12=8y-12+12
-28=8y
-28/8=8y/8
-3.5=y
Another method is to distribute 1/4 to each term within the parentheses.
-10=8y*(1/4) - 12*(1/4)
-10=2y - 3
-10+3=2y - 3 +3
-7=2y
-7/2= 2y/2
-3.5=y
I hope this is helpful!
