a water tank fills through two pipes. water flows in
through one pipe at a rate of 25,000 gallons per hour
and in through the other pipe at a rate of 45,000
gallons per hour. water leaves the system at a rate of
60,000 gallons per hour.
there are 3 of these tanks, and each tank holds
1 million gallons. each tank is half full. water is
entering and leaving a tank at the maximum
amounts. determine the number of hours, x, it will
take to fill all 3 tanks one at a time.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
