What is the inverse of h?

Mathematics

You need to define h(x) to find its inverse.
The general answer is to replace h(x)= with y=. Then you make x the subject of the equation so that you get x= some function of y. That function is the inverse of the original function.
Example: h(x)=2x+5. Write y=2x+5. Now solve for x: x=(y-5)/2 so h⁻¹(y)=(y-5)/2 and h⁻¹(x)=(x-5)/2 is the inverse of h(x).

Twice the product of 3and a number exceeds the sum of the number and 80 by 10.what is the number?
Hatshy [7]
First, create an equation with the criteria given.

If we let x be your number,
2(3x) = 80 + x + 10
(2(3x) is twice the product of 3 and x, and if it exceeds x+80 by 10, then we add 10 to x+80 to make the two sides of the equation equal.)

Now, solve for x.

6x=90+x \\ 5x=90 \\ x=18

Jet001 [13]

Answer:

Lets choose y

  • -8y=3x-24
  • y=-3/8x+3

Plug in

  • 3x+15/8x-15=45
  • 39/8x= 60
  • x=480/39

Celia needs 275 balloons for her mother’s surprise party the balloons only come in a packs of 2.how many packs of balloons will
Lina20 [59]

To find the answer, you will need to divide the total number of balloons by the number of balloons in a pack.

275 ÷ 2 = 137.5

Because you can't buy half of a package, Celia should probably buy 138 packages.
