Atriangle has a height that is five units shorter than its base if b represents the base and h represents the height which of the following equation represents the area of the triangle

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 system of equations. 12x − 18y = 27 4x − 6y = 10
