In exercises 13 - 18 , find the value of x so that the function has the given value. (see example 3.)

-9

The problem:

If h(x)=-7x and h(x)=63, the what is the value of x?

Step-by-step explanation:

h(x)=-7x

You are asked to find x such that h(x)=63.

So you are solving:

h(x)=63 for x:

-7x=63

Divide both sides by -7:

x=63/-7

Simplify:

x=-9

Let's check:

h(x)=-7x

h(-9)=-7(-9)

h(-9)=63

So -9 is the answer.

3 1/3 x 2 3/5 = 8 2/3

step-by-step explanation:

just multiply the first number by the second number to get your answer.

47.28 or 47.2857143

step-by-step explanation:

you just divide 331 by 7 and you get that answer. ( i think so tho)
