Triangle ABCis transformed with the center of dilation at the origin. Pre-image: △ABC with vertices A(−3, 4), B(−1, 12), C(4, −2)

Image: △A′B′C′with vertices A′(−0.6, 0.8), B′(−0.2, 2.4), C′(0.8, −0.4)

What is the scale factor of the dilation that maps the pre-image to the image?

Select the correct answer from each drop-down menu. a system of equations and its solution are given below. system a complete the sentences to explain what steps were followed to obtain the system of equations below. system b to get system b, the equation in system a was replaced by the sum of that equation and times the equation. the solution to system b the same as the solution to system a.]
