Step-by-step explanation:
Every vertex moves twice as far from the center of dilation as it is in the pre-image.
Perhaps the easiest image point to find is the one at lower left. In the pre-image it is 2 units left of the center of dilation, so the image point will be 2×2 = 4 units left of the center of dilation. It will be located at (-6, -2).
Other points on the image can be found either by reference to the center of dilation, or by reference to known image points. For example, the next point clockwise is 1 left and 4 up in the pre-image, so will be 2 left and 8 up from (-6, -2) in the image. That is, the pre-image point (-5, 2) becomes image point (-8, 6). You will note that (-5, 2) is 3 left and 4 up from the center of dilation, and that (-8, 6) is 6 left and 8 up from the center of dilation (twice as far away).
(8,12)(14,3)
Use midpoint formula
(X1+x2/2, y1+y2/2)
Substitute with your points
(8+14/2, 12+3/2)
Solve each
(22/2,15/2)
Cancel common factor 2
(2×(4+7)/2(1),15/2)
Simplify
(4+7/1,15/2)
This is your midpoint
(11, 15/2)
20/x+11=10/x+3
20(x+3)=10(x+11)
20x + 60 = 10x + 110
10x = 50
x = 5
