2. Identify the like terms in the expression.
10 - 3x + 2y + 9x

Use set builder notation to represent the following set: { -3, -2, -1, 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) .

Write and solve a real word problem that involves determining distance on a coordinate plane
