Final answer:
The transformation preserves only distance.
Step-by-step explanation:
The statement that is true about the transformation described is:
The transformation preserves only distance.
When a figure is dilated, the distances between each point on the figure and the center of dilation are multiplied by the same scale factor. In this case, the figure is dilated by a scale factor of 3/2 with the origin as the center. This means that the distance between each point on the figure and the origin is multiplied by 3/2. When the figure is then reflected across the x-axis, the distances are preserved because the figure is flipped and the distances remain the same.
