Answer:
when a point M (h, k) is rotated about the origin O through 180° in anticlockwise or clockwise direction, it takes the new position M' (-h, -k). The signs of the coordinates change .
In the given graph point H' is (-3,-2) .The pre image of this point will be point H .Point H will have coordinates which will have signs of both coordinates opposite to that of point H'.
Coordinates of point H will be (3,2)

Step-by-step explanation:
Triangle LNM is an adjecent interior angle
80/1 = 760/x....80 cd's to 1 vinyl = 760 cd's to x vinyls
cross multiply
(80)(x) = (760)(1)
80x = 760
x = 760/80
x = 9.5.......likely to sell 9 vinyl's
N^3 = 9xxx
20^3 = 8000
21^3 = 9261
