What is 9x9 + 9 - 9 plus 99-9 =

171

Step-by-step explanation:

Recall order of operations.

PEMDAS = parentheses, exponents, multiply, divide, add, subtract

You can treat it like this to make it easier:

((9x9) +9) -9 + (99-9)

(81 + 9) - 9 + (90)

90 - 9 = 81

81 + 90 = 171

6 on both sides and twelve on the top and the bottom

step-by-step explanation:

  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.
