When two of the three numbers are added at a time, the possible sums are 32, 39, 23. what is the sum of all three numbers?
explain.

47

Step-by-step explanation:

Let a, b, and c be those three numbers.

When two of the three numbers are added at a time, the possible sums are 32, 39, 23. Let

Add these three equations:

Divide this equation by 2:

The sum of all three numbers is 47.

  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.
