Three of four numbers have a sum of 22. the four numbers is 8, what is the fourth number?

Step-by-step explanation:

As the sum of three of the numbers is 22, the fourth number is 32 - 22 = 10. The average of the four numbers is 8. This gives the sum of all the four numbers as 8*4 = 32.

  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.

the one that has a slope of 1/2 and is positive.
