Answer:

Step-by-step explanation:

For City A, the expression for temperature change is 9 + (-8)

The amount the temperature changes for City A = 1°F

For City B, the expression for temperature change is -1 + (-3) = -4°F

The amount the temperature changes for City B = -4°F

Step-by-step explanation:

The given information are;

In City A, the temperature rise from 8 am to  9 am = 9°F

In City A, the temperature drop from 9 am to  10 am = 8°F

In City B, the temperature drop from 8 am to  9 am = 1°F

In City B, the temperature drop from 9 am to  10 am = 3°F

The expression for that represents the temperature change from 8 am to 10 am is therefore;

For City A

Temperature change from 8 am to 10 am are

8 am to  9 am = +9°F

9 am to  10 am = -8°F

Sum, change from 8 am to 10 am = 9 + (-8) = 1°F

For City B

Temperature change from 8 am to 10 am are

8 am to  9 am = -1°F

9 am to  10 am = -3°F

Sum, change from 8 am to 10 am = -1 + (-3) = -4°F
