44^4=22^4 . [] find the missing factor in exponential form

The lines shown below are parallel. if the green line has a slope of -1, what is the slope of the red line?

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) .

If x = -2, then x 2-7x+10 equals a. 0 b.20 c.28
