Answer: (5/9, -7/6)</h3>
=======================================================
Explanation:
Since the center of dilation is (0,0), we multiply each coordinate of point B by the scale factor 1/3.
The coordinates of point B are x = 5/3 and y = -7/2
So we have
(1/3)*x = (1/3)*(5/3) = (1*5)/(3*3) = 5/9 as the new x coordinate
and
(1/3)*y = (1/3)*(-7/2) = (1*(-7))/(3*2) = -7/6 as the new y coordinate
The point (5/3, -7/2) moves to (5/9, -7/6)
I think that each shelf will be 19 inches. Because 137 divided by 7 is 19 with the remainder of 4. Half of 4 is 2. Take 2 inches off of each end and that is the 4. So each shelf is 19 inches.
