Answer:
see explanation
Step-by-step explanation:
Under a counterclockwise rotation about the origin of 90°
a point (x, y ) → (- y, x ), thus
P(1, - 1 ) → P'(1, 1 )
Q(3, - 2 ) → Q'(2, 3 )
R(3, - 4 ) → R'(4, 3 )
Answer:
A. Subtract x from both sides: (i.e. 5+x-12 = x-7 <--> 5-12 = -7)
This equation is identically true, so it holds no matter what x is.
