If h(x)=-5-10,find h(-2)

Mathematics
1 answer:
-BARSIC- [3]3 years ago
4 0

I'm going to assume that you meant the equation to be: h(x)=-5x-10


So we're going to take that equation and we're going to solve for h(-2).


This means that we plug in a '-2' for every x in the equation:


h(-2)=-5x-10


h(-2)=-5(-2)-10


h(-2)=10-10


h(-2)=0


So when we solve the equation for h(-2), we get 0 as our answer.

Sergeu [11.5K]

Answer:

She earns $4 x is representing the hours.

Step-by-step explanation:

16 is the charge up front.
