Dilation involves changing the size of a figure
The endpoints of the image are (0,3) and (8,3)
<h3>How to determine the coordinates of the image</h3>The coordinates of the pre-image are give as:
(2,2) and (6,2)
The scale factor is given as:
k = 2
The center of dilation is given as:
(a,b) = (4,1)
The coordinates of the image are then calculated as:
(x,y) = (k(x -a) + a, k(y -b) + b)
For (2,2), we have:
For (6,2), we have:
Hence, the endpoints of the image are (0,3) and (8,3)

For this case we have the following inequality:
We multiply both sides of the equation by -1.
By doing this, change the symbol of the inequality.
We have then:
From here, we clear the value of x.
We have then:
Answer:
The solution set is:
{x | x R, x < -12}
We multiply both sides of the equation by -1.
By doing this, change the symbol of the inequality.
We have then:
