It is the last one.
A pre-image is the original before another shape is created from it, either dilated, translated, reflected, or rotated.
1/2 (6x - 10) + 10 = 5x - 13
(6x/2) - (10/2) + 10 = 5x - 13
3x - 5 + 10 = 5x - 13
3x - 5x = -13 + 5 - 10
-2x = -18
x = -18 / -2
x = 9
D.) x = 9
360/60 = 6
6 degrees every second
6*20 = 120 degrees
120 degrees after 20 seconds
6 * 45 = 270
270 degrees after 45 seconds
Hope I helped!
