Question

The temperature, t, in burrtown starts at 25 F at midnight, when h= 0. For the next few hours the temperature drops 3 degrees every hour. Which equation represents the temperature, t at hour H?

A.) t= 3h + 25

B.) t= 25h - 3

C.) t= -3h + 25

D.) t= -25 + 3

Answer 1

Here is the equation: t=-3h+25
there u go

Answer 2

C) t = -3h + 25

Explanation:

The temperature (t) has a linear relationship with the time (h) according to the following expression.

t = m.h + b

where,

m is the slope

b is the y-intercept

The slope represents the rate of change of the temperature with respect to the time, that is, -3°C/h, so m = -3.

The equation is

t = -3h + b

When h = 0, t = 25. Then,

25 = -3 × 0 + b

b = 25

The final equation is

t = -3h + 25
