The average rate will be:  0.7 inches/hour

Hence, Option (4) is correct.

Step-by-step explanation:

As the average rate = change in y-values/change in x values

                                 = Δy/Δx

From the table, it is clear that over the time interval 't=2' to 't=7', the values

snow depth 'd' inches change from d=1.5 to d=5.

Therefore,

Average rate = Δy/Δx

                      = (5-1.5) / (7-2)

                      = 3.5/5

                      = 0.7 inches/hour

Therefore, the average rate will be:  0.7 inches/hour

Hence, Option (4) is correct.

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
