100 POINTS!!! A triangle with vertices at A(20, -30), B(10,-15), and C(5,-20) has been dilated with a center of dilation at the origin.
The image of B, point B', has the coordinates (2, -3). What is the scale factor of the dilation?
05
5
10

anyone? find the second, fifth, and ninth terms of a sequence where the first term is 65 and the common difference is -7. 72, 93, 121 72, 79, 86 58, 37, 9 58, 51, 44

Which term best describes the association between variables a and b

To describe a sequence of transformations that maps triangle abc onto triangle a"b"c", a student starts with a reflection over the x-axis. how should the student complete the sequence of transformations to map triangle abc onto triangle a"b"c"? plz
