Given

Tom has a goal of saving enough money to buy a new set of rims for his car.

Tom makes $7. 50 an hour take home pay at his job working 15 hours per week.

The earning of Tom in an hour = $7.5

If tom worked 15 hours in a week, then the amount earned by him in one week is;

=15\times 7.5\\\\=112.5

The required amount to achieve his goal = $900

The number of week he need to work to achieve his target is;

= \dfrac{900}{112.5}\\\\= 8

Hence, It will take 8 weeks to Tom to achieve his goal.

If x is divided by 2 and then 4 is subtracted, then the function is f left parenthesis x right parenthesis equals x divided by 2
Anni [7]

The inverse is y = x/2 - 4

Steps involved are -

  1. replace f(x) with y:   y = 2(x + 4)
  2. Then switch y and x:   x = 2(y + 4)
  3. Finally make y the subject:
  4. x = 2(y + 4)
  5. x/2 = y + 4      (divide by 2)
  6. x/2 - 4 = y       (subtract 4)
  7. So, the inverse is y = x/2 - 4

<h3>What is the formula for inverse function?</h3>
  • In mathematics, the inverse function of a function f (also called the inverse of f) is a function that undoes the operation of f.
  • The inverse of f exists if and only if f is bijective.
  • f-1(y) = y/2 = x, is the inverse of f(x).
