You would take 3 into 7.5 to get that scale factor.
Answer:
125
Step-by-step explanation:
125 divided by 5 is 25, and 25 is 1/4 of 100
Answer:
(-9,3)
Step-by-step explanation:
6x and -6x cancel, leaving us 12y=36 which means y=3. Then we can plug it back into our equations leaving us with x=-9.
We are said that a rectangle has been transformed into the one indicated in Figure 1 according to this rule:

We know that the center of rotation is origin and two rules are applied to rotate a point 90 degrees, namely:
1. Clockwise
In this case, the rule to transform a point is:

This rule was already applied to form the image, so all we need to do is to reverse the answer using this formula, therefore:

2. Counterclockwise
Applying the same previous concept but with the new rules for this case:

By reversing the answer, we have:
