Asquare has sides 10x. write and simplify an expression for the perimeter of that square.
a rectangle has a length of 2x+7 and a width of 3x+8y. write and simplify an expression for the perimeter of that rectangle.

  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.

x=30
