Which of the following represents a first step in solving the equation (x-6)^2=9?
a. x-6=3
b. x-6=9
c.(x-6)^2=3
d. x-36=9

First step is square root both sides leaving with
x-6=+/-3

closest one is A

answer is A

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
