What is the mapping notation for translating point (x, y) down 3 units?
A.
(x, y+3)
B.
(x-3,y)
C.
(X+3,y)
D.
(x, y-3)

D.(x,y-3)
Because x basically represents the horizontal and y represents vertical

D because when it goes down the y axis and is negative

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!

1+1=22×1=22-1=11-1=1duh
