The answer is 127/24 or 5.2916
Answer:
For 100 calls the monthly cost = 10.95 + 0.95(100) = $ 22.95
120 calls = 10.95 + 0.95(120) = $ 25.35
140 calls = 10.95 + 0.95(140) = $ 27.75
160 calls = 10.95 + 0.95(160) = $ 30.15
Therefore it is constant
The answer is B. Yes, the average rate of change is constant
Hope this helps!
EXPLANATION
When x=6 and y=13 x+y = 6 + 13 = 19

Answer B. 24
Each loaf of bread is divided into 4 slices
And there are 6 loaves of bread
6 x 4 =24
24 pieces
F(x) = 3x+1
G(x) = X^2 - 6
F(G(x)) = F(X^2 - 6) = 3(X^2 - 6) + 1 = 3X^2 - 18 + 1 = 3X^2 -17
F(G(x)) = 3X^2 - 17
