Ratio is 7:9
add the ratio it becomes 16
272 members divided by 16

Find g^−1 (x) when g(x) = 3/5 x −9. 5/3x − 1/9 5/3 x + 9 −3/5 x+ 9 5/3 x + 15

Cerrena [4.2K]

Answer:

5/3 x + 15

Step-by-step explanation:

The inverse of a function is the reflection across the line y = x. As such, algebraically it is found by switching y and x in the equation and isolating to solve for y.

g(x) = 3/5 x - 9

x = 3/5 y - 9

x + 9 = 3/5 y

5(x+9) = 3y

(5x + 45)/3 = y

5/3x + 15 = y
