Does the table represent a function? why or why not?

1. are the triangles similar and if so why? what is the value of x? show your work.

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) .

Solve this and show you’re work step by step ! -5 3/4+3h< 9 1/4 -
