What is the inverse of the function f(x) = 2x - 10?
aliya0001 [1]

Answer:

h(x) = \frac{1}{2} x+ 5

Step-by-step explanation:

To find the inverse of a function, simply switch the 'x' and 'y' variables. Substitute in 'y' in the place of f(x) for this purpose:

y = 2x - 10

Switch positions:

x = 2y - 10

Add '10' to both sides to begin simplifying:

x + 10 = 2y

Divide both sides by 2:

y= \frac{x+10}{2}

This can be rewritten as:

y = \frac{1}{2} x+ 5

Therefore, the inverse of the function is:

h(x) = \frac{1}{2} x+ 5

Michael read 135 pages in 1 1/2 hours, Select all of the rates that are equivalent to this rate
devlian [24]

The rates that are equivalent to this rate is 90 pages/hr

<h3>Rate of change</h3>

The rate is the number of pages Michael read in 1 hour.

If he read 135 pages in 1 1/2 hours then;

  • 135 pages = 1.5 hours

To determine the rate, we will have:

  • x = 1 hour

Divide both expressions:

135/x = 1.5/1

1.5x = 135

x = 135/1.5

x = 90

Hence the rates that are equivalent to this rate is 90 pages/hr
