Find the value of x to the nearest tenth

20.8

Step-by-step explanation:

Using Pythagorean theorem, you can find 1/2 of x.

12²= 6² +1/2x²

From this we find 1/2 x is ≈ 10.4

Then x itself would be 2 times that, resulting in 20.8, that is your 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.
