y=-27/9
y=-3
Answer:
A. H(x) is an inverse of F(x)
Step-by-step explanation:
The given functions are:
We compose F(x) and G(x) to get:
Hence G(x) is not an inverse of F(x).
We now compose H(x) and G(x).
We simplify to get:
Since , H(x) is an inverse of F(x)
Answer:
∠B = 60°
Step-by-step explanation:
They are supplementary angles, which means they add up to 180°.
∠B + ∠A = 180
? + 120 = 180
? = 180 - 120
? = 60°
