Abd and dbc form a linear pair, and abd and cbe are vertical angles. if abd = 2(5x-11), m dbc = 2x+10, and cbe = 2/3y + 36, select all the statements that are true

(hurry! ) which expression is equivalent to the following complex fraction?

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) .

Which of the following is correct interpretation of the expression -4+13
