Answer:
(21)+(6) is an equivalent expression
Step-by-step explanation:
(7x3)2(x3)
(21)+(6)
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>
