Answer:
(g o f)(x) =
(not simplified)
Step-by-step explanation:
(g o f)(x) = g(f(x))
g(x) =
f(x) = 
g(f(-5)) = g(
=
= 
g(-170) =
= 
Answer:
x + 3 = 0.
Step-by-step explanation:
One would be:
x + 3 = 0 Subtract 3 from both sides:
x + 3 - 3 = 0 - 3
x = -3
5.70c + 9.80a = 1526.60
a = 4c
5.70c + 9.80(4c) = 1526.60
5.70c + 39.20c = 1526.60
44.90c = 1526.60
c = 1526.60/44.90
c = 34 <=== child tickets sold
a = 4c
a = 4(34)
a = 136 ...adult tickets sold
