A fisherman leaves his home port and heads in the direction N 70°W. He travels 30 miles. How far north and how far west is he from his home port?

Segment xz is bisected by point y. if xy = 12x, and the measure of xz = 18x – 6, solve for x

Me because some of question i don’t understand

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) .
