hey guys i hope you all get what you want, but now i need help, um so what year was the first christmas?

Which expression is equivalent to? assume x > 0 and y > 0.

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, –6) is rotated 90° counterclockwise. (x, y) → (–y, x) 1. switch the x- and y-coordinates: (6, –3) 2. multiply the new x-coordinate by –1: (6(–1), –3) 3. simplify: (–6, –3) .

If y varies directly as x2 and y=6 when x=6, find the constant of variation.
