On a very cold morning it was - 7 Fahrenheit as the day went on the temperature rose 3° each hour which equation shows the temperature over time

T = - 7 + 3t.

Step-by-step explanation:

T = - 7 + 3t where T = the temperature and t = the times in hours.

Step-by-step explanation:

as the day went on the temperature rose 3° each hour. This is a linear rate. The rate at which the temperature is increasing is in arithmetic progression. The formula for determining the nth term of an arithmetic sequence is expressed as

Tn = a + (n - 1) d

Where

a represents the first term of the sequence.

d represents the common difference.

n represents the number of terms in the sequence.

From the information given,

a = - 7 Fahrenheit

d = 3 degrees Fahrenheit

n = number of hours over time

The equation that shows the temperature over time would be

Tn = - 7 + (n - 1) 3

Tn = - 7 + 3n - 3

Tn = - 10 + 3n
