X^2 -18x +81=0 factor it

x=9

Step-by-step explanation:

81 is the product of -9 & -9. -9-9=-18. Therefore, (x-9)^2=0, and you get that x=9.

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )
