Answer:

  f^{-1}(x)=\dfrac{x-3}{2}

Step-by-step explanation:

To find the inverse function, solve for y:

  x = f(y)

  x = 2y +3

  x -3 = 2y

  (x -3)/2 = y

The inverse function is ...

  \boxed{f^{-1}(x)=\dfrac{x-3}{2}}

A ski rental store rents a pair of skis for $44 a day and a snowboard for $58 a day. Yesterday, the store made $2,232 on ski and
Katen [24]

First, let the number of skis rented by x and the number of snowboards rented by y. We can then assemble the first equation from the amount of money made from the rentals.


44x + 58y = 2232


The second equation can come from the fact that 9 more skis were rented than snowboards.


y = x - 9


Therefore our system is:


44x + 58y = 2232

y = x - 9
