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

Answer:
Distance = 13
Step-by-step explanation:
Using the distance formula, plug in the two points:
d = sqrt(9-(-3))^2+(-3-2)^2
d = sqrt(12)^2+(-5)^2
d = sqrt144+25
d = sqrt169
d = 13
Y = 4x - 3 - x^2
now sub that in for y in the other equation
x + y = 1
x + 4x - 3 - x^2 = 1
-x^2 + 5x - 4 = 0
(-x + 1)(x - 4) = 0
-x + 1 = 0 y = 4x - 3 - x^2
-x = -1 y = 4(1) - 3 - 1^2
x = 1 y = 4 - 3 - 1 = 0
x - 4 = 0 y = 4x - 3 - x^2
x = 4 y = 4(4) - 3 - 4^2
y = 16 - 3 - 16
y = -3
points that satisfy this are : (1,0) and (4,-3)
