Answer: (-2,4)
Step-by-step explanation:
Take the average of the x-coordinates and the average of the y-coordinates
(1-5)/2=-2
(1+7)/2=4
Answer:
D: f(g(-1)) = 1/2
Step-by-step explanation:
f(x) = 1/(x + 1)
g(x) = x²
g(-1) = 1
f(g(-1)) = 1/(1 + 1)
f(g(-1)) = 1/2
7(8x+3) = 56x+21
8(8x+4) = 64x+32
4(8x+4) = 32x+ 16
