18. If 4 - 5x = -3, then what is 10x - 8

Find the value of tan theta if sin theta = 12/13 and theta is in quadrant 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) .

Write the point-slope form of the line passing through (2, -12) and parallel to y=3x.
