To solve this problem you must apply the proccedure shown below:
1. You must multiply the coordinates of
by the scale factor given in the problem above. Therefore, you have that the coordinates of
are:

2. The midpoint of
has the folllowing coordinates:

3. The center of dilation is a fixed point, with coordinates
. Therefore, the distance from the center of dilation to the midpoint of
is:

The answer is the option C: 
Answer:
-3x^2+7x+6
Step-by-step explanation:
Answer:
-7y > 161
7y < -161
y < -23
7y > -161
y > -23
So, your answer is: -7y > 161 is equal to y < -23, and 7y > -161 is equal to y>-23.
