(5 points) part b: simplify the expression and explain, using words, what your answer means. (5 points)

(A) The expression to show the average change in the temperature of the city each week is . (B) The simplified form of the expression is .

Explanation:

Part A:

It is given that the temperature of a city changed by -24 degrees Celsius over a 6-week period. The temperature changed by the same amount each week.

Let the change in the temperature per week be x.

The change it the temperature in 6 week is 6x.

From the given information the temperature of a city changed by −24 degrees Celsius over a 6-week period.

Therefore, the expression to show the average change in the temperature of the city each week is .

Part B:

We have,

After simplification the expression is . It means the temperature of a city changed by -4 degree celsius per week or the temperature decreased by 4 degree celsius per week.
