Leilani is practicing with a geometry tool to copy segments. The segment AB is dilated by a scale factor of k=2 with a center of dilation at the origin. She then reflects the dilated segment over the y-axis, then dilates the reflected segment with a scale factor of 1/2 with a center of dilation at C = (5, 5) to get the segment A'B'. What are the coordinates of segment A'B'?
