Trapezoid k is the image of trapezoid k after a series of transformations. bella and marco described the sequence of transformations in different ways. bella’s sequence marco’s sequence 1. a dilation of trapezoid k by a scale factor of mc021-3.jpg with the origin as the center of dilation 2. a rotation of mc021-4.jpg about the origin 3. a translation of 1 unit down 1. a reflection of trapezoid k across the x-axis 2. a dilation by a scale factor of mc021-5.jpg with the origin as the center of dilation 3. a translation of 1 unit down which sequence or sequences are correct and why? only bella is correct. only marco is correct. both bella and marco are correct because both chose the correct scale factor for the dilation and both describe other transformations that could be used. neither bella nor marco is correct because the scale factor they chose for the dilation is incorrect.
