Answer:
B' (2, 5 )
Step-by-step explanation:
Under a counterclockwise rotation about the origin of 270°
a point (x, y ) → (y, - x ) , then
B(- 5, 2 ) → B' (2, 5 )
2t > 324
divide each side by 2
2t/2 > 324/2
t > 162
12y >= 1
divide each side by 12
12y/22 >= 1/12
y >= 1/12
x/9.5 < 11
multiple each side by 9.5
x/9.5 * 9.5 < 11 * 9.5
x < 105.5
