Worker a can a task in 9 hours while worker b can complete the same task in 4 hours. how long (in hr) would it take the workers to complete the task together? ( enter an exact number as an integer, fraction, or decimal.)

Step-by-step explanation:

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.
