if two inlet pipes can fill a pool in one hour and 30 minutes, and one pipe can fill the pool in two hour and 30 minutes on its own, how long would the other pipe can fill the pool on its own?

the answer is c. 23/3

  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.
