Question

I don't get how to answer
"h(x)= -7x; h(x) = 63" to find the value of x. I know that h(x) means that h is a function of x, and to solve the single problems like f(x) = x+6, buts that's all. Can y'all help me :)

Answer 1

Strikes me as a strange problem. Here your function h(x) is defined in two different ways:

h(x) =-7x and h(x) = 63. h(x) obviously equals h(x), so one could conclude that -7x=63. What is the value of x that satisfies this?

Answer 2

Exactly. Let me send a link to show.

Answer 3

Show what?

Answer 4

Since for some reason it doesn't work, I'll write down.
In Exercises 13-18, find the value of x so that the function has the given value.
13. h(x) = -7x; h(x) =63
14. t(x) = 3x; t(x) = 24
Etc.....

Answer 5

You have to solve the value of x

Answer 6

for
h(x) = -7x; h(x) =63

they are saying if h(x) is 63 , and h(x) is -7x then
-7x = 63
and we want to know what "x" value causes h(x) to be 63

in this case, divide both sides by -7
\[ \frac{-7}{-7} x = \frac{63}{-7} \\
x = -9 \]

as a check:
using h(x)= -7x
then h(-9) = -7*-9 = 63
so it checks out.
