How do you know that the sum of (-2 3/4) and 5/9 is rational

The sum is a fraction

Step-by-step explanation:

I just did this yesterday so i know its correct!

-2 3/4 + 5/9

-2 3/4 = -11/4

-11/4 + 5/9

-11/4 = -99/36

5/9 = 20/36

-99/36 + 20/36

99 - 20 = 79

-99/36 + 20/36 = -79/36

-79/36 = -2 7/36

Let me know if this is the correct answer. :)

  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.
