Question

What are the answer to this question

Answer 1

`t=-3h+25`

Explanation:

If we know that when
`h=0`,
`t=25`, then we can use a direct proportion equation (
`x=ky`). The temperature decreases every hour by 3 degrees. However, we know that before any temperature drop, the temperature was 25 degrees. All together, this gives us
`t=-3h+25`, where
`-3h` is the temperature drop each hour, and
`25` is the starting temperature. Hope that explained things :)

Answer 2

Answer: t=-3h+25

Explanation:

t=-3h+25

25 degrees is a constant-- it never changes, no matter how many hours goes by. So, you don't multiply a variable with it.

The temperature drops every 3 hours-- this is not constant, since it's dependent on the number of hours that passes. So, use a variable here. Since the temperature drops every three hours, it's -3, and not 3.
