Question

22. the blue figure is a dilation image of the black figure. The center of the dilation is O. Tell whether the dilation is am enlargement or a reduction. Then find the scale factor

Answer 1

Since I can't view the image you attached, I'll just provide you a guide for solving the scale factor:


To find a scale factor between two similar figures,find two corresponding sides and write the ratio of the two sides. If you begin with the smaller figure, yourscale factor will be less than one. If you begin with the larger figure, your scale factor will be greater than one.

Answer 2

Answer:

In the figure we can see that the dilation is an enlargement from the black figure to the blue figure.

The factor would be found by taking two points and dividing them. For example, at the right side we have that the point was from x=2 to x=4, their division would be 4/2=2. Now, we take the point in the left side x=-1 and x=-2, if we divide them we have -2/-1=2.

Therefore, the scale factor is 2.
