The area of a rectangle is 15 square inches. what will be the area, in square inches, of the rectangle after it is dilated by a scale factor of 2?

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) .

Through non-collinear points there is exactly one plane.

What are the solutions of the system? solve by graphing. y = -x^2 - 3x + 2 y = -2x + 2
