<span>In the question "Which equation results from taking the square root of both sides of (x – 9)2 = 81?" The correct answer is x - 9 = +/- 9.
Taking the square root of both sides of the equation (x - 9)^2 = 81 will give:
sqrt(x - 9)^2 = sqrt(81)
x - 9 = +/- 9
Solving the equation results in two equation:
x - 9 = 9 and x - 9 = -9
x = 9 + 9 and x = -9 + 9
x = 18 and x = 0</span>

Answer:
80,000 + 6,000 + 500 + 3
Step-by-step explanation:
Expand so that all non-zero digits are by itself. Remember to retain it's place value:

Answer:
use y=mx+b format to find the y-intercept
Step-by-step explanation:
the y-intercept is b of course
the y-intercept is where the y meets a line
the equation will be _=_x+_
