Please someone help I need help been stuck on this for the longest

a.) 16

b.) 8

Step-by-step explanation:

a. how much lower was the 6am temperature in Nome than in Wyoming

Essentially this question is asking us to find the difference of the temperatures of Nome and Wyoming at 6am

Temperature of Nome at 6am: -31

Temperature of Wyoming at 6am: -15

Difference between two temperatures: -31 - (-15)

The two negative signs cancel out and the sign changes to +

-31 + 15 = -16

The temperature in Nome was 16 degrees lower then in Wyoming

b. At noon the temperature of Boston had risen by 14 degrees. what was the temperature of boston at noon.

All we have to do for this one is add 14 to the temperature of Boston at 6am. ( This is because the question tells us the temperature has risen 14 degrees by noon )

-6 + 14 = 8

At noon the temperature would be 8 degrees in Boston.

C.

Step-by-step explanation:

(1, 4)

The y coordinate is swapped with the x coordinate, using the rule (x, y) to (-y, x). This also means that the y coordinate is now negative.

(1, 4) to (-4, 1)
