(–2)(3) + (–0.1)(0.4)
(2.1)(3) – (2.1)(0.4)

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) .

Two numbers have a sum of -19. one number is x. what expression represents the other number?

Will give a: 122 b: 90 c: 48 d: 180
