Marla has a piece of fabric. She cuts off 8 inches and makes a bow for each of the dogs she grooms. Today she groomed 12 dogs. Write and find the value of an expression to show the change in the length of the fabric. *

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) .
