B = (4, 2), B = (2, 1); House dimensions: 25ft by 15ft, Question 10. b. ratio of y-coordinates = 2/1 = 2 The figure is dilated by a factor of 2, but the orientation of the figure in the coordinate plane is rotated 180, Question 1. D: (x, y) (\(\frac{1}{2}\)x, \(\frac{1}{2}\)y) Question 1. a = 15/3 ______ units, Question 6. _____________, Answer: There must be an even number of dilations and for each dilation applied to the figure, a dilation that has the opposite effect must be applied as well. MNOP has vertices at M(4.5, 6), N(9, 6), O(9, 10.5), and P(4.5, 10.5). (2, -2) How can you use dilations to solve real-world problems? The scale factor of the dilation is 2. The business owner would like it on the top. There must be an even number of dilations and for each dilation applied to the figure, a dilation that has the opposite effect must be applied as well.
