Answer:
CD
Step-by-step explanation:
CD is perpendicular to XY and also cuts XY into two equal halves.
FH is not perpendicular to XY even though it cuts XY into two equal halves.
DH is not a line.
FG is perpendicular to XY but it does not cut XY into equal halves.
Answer:CD
x = 5 ±
Given
x² - 10x + 25 = 17 ← left side is a perfect square, thus
(x - 5)² = 17 ( take the square root of both sides )
x - 5 = ± ( add 5 to both sides )
Thus
x = 5 -
x = 5 +

Really Hope This Helps :D
Step One: Identify two points on the line.
Step Two: Select one to be (x1, y1) and the other to be (x2, y2).
Step Three: Use the slope equation to calculate slope.
(Equation For Step Three is y=mx+b where m is the slope and b is the y-intercept.
Enjoy :D
