Question

On a very cold morning,it was -7%f.As the day went on,the temperature rose 3 degrees each hour.Which equation shows the temperature over time?

Answer 1

Answer:

The equation that shows the temperature over time is t(x) =  -7 + 3x

Step-by-step explanation:

Given:

Temperature at every morning =    -7°F

Rise in Temperature per hour = 3 degrees

To Find:

Equation that shows the temperature over time

Solution:

Let x be  the time (hours)

Now the temperature at time x (hours)  is

=> $-7 + (\text{Number of hours} \times \text {Increase in temperature per hour)}}$

=>-7 + 3x

Hence at time x hours the temperature will be

t(x) =  -7 + 3x
