Rachel is planning to run an average of 6.4 miles over three consecutive days. on the first day, she ran 6.6 miles, and on the second day, she ran 6.5 miles. what is the maximum number of miles rachel can run on the third day without going over the planned average of 6.4 miles per day?

Given:

The coordinate of point R in quadrilateral RUST are (2,4).

R is dilated by a scale factor of 3, centered at the origin, followed by the translation .

To find:

The coordinates of R' after dilation and translation.

Solution:

If a figure is dilated by a scale factor of 3, centered at the origin, then

We value R(2,4).

The rule of translation is:

Using this rule, we get

Therefore, the coordinates of point R' are (10,12) and the correct option is B.
