-72 is the final answer

Answer 2

Answer:

Step-by-step explanation:

You are giving away a lot of points. Usually 20 will attract our attention. I mean you put up 20 and we get 10. It's enough.

h(t) = - 20 + 13t

• First of all you need to understand that h(t) is a y value.
• The t is the x value.
• So when you see something in h(t)s value that isn't t, that's what you put in the value for t on the right side. That's the key to the problem.

In this case t is going to be - 4

h(-4) = -20 + 13(-4)

h(-4) = -20 - 52

h(=4) = -72
