The monthly cost (in dollars) of water use is a linear function of the amount of water used (in hundreds of cubic feet, HCF). The cost for using 14 HCF of water is $ 32.68 , and the cost for using 52 HCF is $ 95.38 . What is the cost for using 19 HCF of water?

$40.93

Step-by-step explanation:

Linear function of:

To find:

Linear equation in slope-intercept form:

We have points of: (14, 32.68), (52, 95.38):

Using the points we can find the value of m and b:

Then finding b:

So the function is:

Then y(19) is found as:

Cost of 19 HCF of water is $40.93

4

step-by-step explanation:

6 (donuts) divided by 3 is 2.

so 2/3 means 2 times 2, which is 4/6.

you get two and your friend gets four.

the answer is -6

step-by-step explanation:

the answer is -6 because its next to the variable m
