Answer: 9+d=x or x=9+d
d-the new dvds
x-the unknown total
9-the dvds Zeke owned before
9 = 25%
25% * 4 = 100%
9 * 4 = 36
There are 36 cotton candy cones in total.
For h(x) = -7x + 10, x =1
For r(x) = 4/5x+ 7 , x = -15
Step-by-step explanation:
in order to find the value of x on which the functions will have given values, we will put the functions equal to the given values
So,
<u>h(x) = -7x + 10; h(x) = 3</u>

Dividing both sides by -7

<u>r(x) = 4/5x+7; r(x) = -5</u>

<u></u>
