Find the value of x.

16

Step-by-step explanation:

don't let the x confuse you. remember add up all the corners of the triangle to get 180.

(9x-8) + (x+10) + (x+2) = 180

add all numbers by themselves and add the variables together

9x + x + x = 11x

-8+10+2=4

11x + 4 = 180

11x = 176

x= 16

  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.
