Step-by-step explanation:
Under a rotation about the origin of 90°
a point (x, y ) → (- y, x ), thus
C(6, 6 ) → C'(- 6, 6 )
D(6, 8 ) → D'(- 8, 6 )
E(8, 10 ) → E'(- 10, 8 )
F(10, 8 ) → F'(- 8, 10 )
−10x + 1 + 7x = 37
combine like terms
-3x + 1 = 37
subtract 1 from both sides
-3x = 36
divide both sides by (-3)
x = - 12
Answer
x = - 12
