Inverse Functions (please help)

The procedure for this case is add three, then divide by 5.

Step-by-step explanation:

if y=5x-3

to find the inverse, we exchange x and y then solve for the new y.

x=5y-3   add 3

x+3 = 5y   divide by 5

(x+3)/5 = y

or

inverse, y=(x+3)/5

The procedure for this case is add three, then divide by 5.

15% chance.

step-by-step explanation:

3/10 times, the 5 year old will get a tablet. 5/10 times, the 13 yer old will get a tablet. multiply both fractions to get 15/100 times, both would have a tablet.
