Answer:

12

Step-by-step explanation:

Start by expanding the expression:

4(3x+5)

Distribute the 4 to each of the numbers in the parentheses

12x+20

The coefficient of x is basically what is being multiplied by x. In this scenario, we can expand 12x to be...

12*x

Which means that the coefficient of x is 12

What is the inverse of the function f(x) = 2x + 1?
timama [110]

Answer:

  (a)  h(x) = 1/2x -1/2

Step-by-step explanation:

The inverse of the function y = f(x) is found by solving x = f(y).

__

<h3>setup</h3>

  x = f(y)

  x = 2y +1 . . . . . . use the definition of f(x)

<h3>solution</h3>

  x -1 = 2y . . . . . subtract 1

  (x -1)/2 = y . . . . divide by 2

  y = 1/2x -1/2 . . . . eliminate parentheses

  h(x) = 1/2x -1/2 . . . write in functional form

The inverse of f(x) = 2x+1 is ...

  h(x) = 1/2x -1/2
