In City A, the temperature rises 4F from 8 A. M. To 9 A. M. Then the temperature drops 7F from 9 A. M. To 10 A. M. In City B, the temperature drops 6F from 8 A. M. To 9 A. M. Then the temperature drops 2F from 9 A. M. To 10 A. M. Write an expression that represents the change in temperature from 8 A. M. To 10 A. M. For each city. Simplify and interpret each sum.

Follows are the solution to this question:

Step-by-step explanation:

The general term for temperature variations from 8 am to 10 am:  

Where represents a transition throughout the time interval subscribed to.  

In this, the city of A:  

In this, the city of B:  

It decrease of 3°  (non-value) overall in city A.  

Temporarily, in city B, is 8° C. City B has a greater temperature change (8 vs. 3) between A and B.
