Explanation:

12:00-10*

1:00-8*

2:00-6*

3:00-4*

4:00-2*

5:00-0*

6:00-(-2*)

7:00-(-4*)

8:00-(-6*)

9:00-(-8*)

Answer 2

Answer:

Let noon be time t = 0 hr.,

then the temperature T in degrees Celsius at t hr. would be:

T = 10 - 2t

Now,

To find when the temperature is 8°C below zero,

T = -8

10 - 2t = -8

2t = 18

t = 9

Thus, the temperature is 8°C below zero at 9:00 pm.

To find the temperature at midnight,

use t = 12:00

T = 10 - 2(12) = 10 - 24 = -14

Thus, the temperature at midnight is 14∘C below zero.

Hope this helps you...
