Point a is the pre-image of a vertex of a square and is located at (–10, 8). the square is dilated with the center of dilation at the origin. point a’ is the image and is located at (–7.5, 6). what is the scale factor of the dilation?

the scale factor would be .75 or 3/4

.75

Step-by-step explanation:

one of each metals

step-by-step explanation:

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.
