So first, we multiply out the brackets.
-15x - 18 + 2 = 17 + 16x -1
Then, bring all the terms onto one side so you can solve.
-15x-18+2-17-16x+1=0
Then, we simplify this.
-31x-32=0
Then, isolate x
-31x=32
x=32/-31 or -1.03 (nearest hundredth )

Find an equation for the inverse of the function. F(x)=5x+1
Ksenya-84 [330]

Answer:

f-1(x) = (x - 1)/ 5.

Step-by-step explanation:

Lete f(x) = y = 5x + 1

Now we find an expression for x in terms of y:

y = 5x + 1

5x = y - 1

x = (y - 1) / 5

So the inverse of th function = f-1(x) = (x - 1)/ 5 (answer).
