Find the inverse function of f(x) = 5x-4. Show your work.

The inverse is (x+4)/5

Step-by-step explanation:

f(x) = 5x-4

Let f(x) =y

y = 5x-4

Exchange x and y

x =5y-4

Solve for y

Add 4 to each to each side

x+4 = 5y-4+4

x+4 = 5y

Divide each side by 5

(x+4)/5 = 5y/5

(x+4)/5 =y

The inverse is (x+4)/5

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
