Scientists are studying the temperature on a distant planet. they find that the surface temperature at one location is 40° celsius. they also find that the temperature decreases by 3° celsius for each kilometer you go up from the surface.
let t represent the temperature (in celsius), and let h be the height above the surface (in kilometers). write an equation relating t to h,

T(h) = 20 - 3h

Step-by-step explanation:

We are told that for every km you go up, the temp goes down 3°.

Let's say you go up 1km, then the temp should be 17°. We can easily represent it by the equation: T(h) = 20 - 3h

If we go up 1km: T(1) = 20 - 3*(1) = 20 - 3 = 17°

If we go up 2km: T(2) = 20 - 3*(2) = 20 - 6 = 14°

If we go up 3km: T(3) = 20 - 3*(3) = 20 - 9 = 11°
