Answer:
a = 15
Step-by-step explanation:
g(x) is the same thing as "y". Our point gives us an x and y value, so we will sub those into the equation and solve for a:
-2 = a(1/3) - 7 and
-2 = 1/3a - 7 and
5 = 1/3a so
a = 15
Answer:
1) There were 120 customers per night when the restaurant opened
2) y = -2x + 24
Step-by-step explanation:
