12 - 4n = 20
What’s the answer it says solve for n?

Step-by-step explanation:

20-12=8

8-4= 4

4*5=20

5

This is just a guess

  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.
