40 and 20 lol 40 is 2/3 of 60 and 20 is 1/3
the transformation (x, y) → (x, y- 4) , means the x-coordinate remains unchanged, while the y-coordinate has 4 subtracted from it, for example
the points on the diagram
A(1, 5 ) → A'(1, 5 - 4) → A'(1, 1)
B(4, 5) →B'(4, 5 - 4) → B'(4, 1)
C(4, 3) → C'(4, 3 - 4) → C'(4, - 1)
D(2, 2) → D'(2, 2- 4) → D'(2, - 2)
Answer- (-8,7) if you reflect over the x axis the c value stays the same and the y value flips
-2 -1 0 1 2 3
7 5 3 0 -1 -3
1. The mean of all the numbers is 41.
5. Median : 52
