Answer:
12
Step-by-step explanation:
To find the inverse we swap y and x and solve for y:
x = 9y + 15
x - 15 = 9y
y = (x-15)/9
Last choice
Answer:
D. –10
Step-by-step explanation:
Given equation:
y = 3x – 1
what is the value of y when x equals –3?
Substitute x = -3 into the equation to find y
y = 3x – 1
= 3(-3) - 1
= -9 - 1
= -10
y = -10
The correct answer is D. –10
Answer:
70
Step-by-step explanation:
If g(x) =x^2 -1, then
f[g(5)] = 3*(5^2-1) -2 =72-2= 70
