Easy
(g o f)(-5)=g(f(-5))
first evaluate f(-5), then input the result into g(x)
f(-5)=-2(-5)-7
f(-5)=10-7
f(-5)=3
g(3)=-4(3)+6
g(3)=-12+6
g(3)=-6
(g o f)(-5)=-6
Answer:
popcorn is usually around 5 dollars and a drink is 3 so: 5 x 3
Step-by-step explanation:
B. 8+(-10)
Explanation:
8-10 is -2
If you try all the answers, 8+-10=-2
Perpendicular means the slopes are opposite inverse of each other
If line a is slope 2, the perpendicular line to Line a would have a slope - 1/2
Difference in y over difference in x gives slope. If they are opposite inverse values the lines are perpendicular. ( in this case the answer is true.)
