The flow rate of a water pump is 2.8 gallons per minute. how many minutes does it take this pump to transfer 84 gallons of water out of a swimming pool?

30

Step-by-step explanation:

Divide 84 by 2.8 which equals 30

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
