SOCORRO represente na reta numerica os seguintes suconjuntos de R a) A={x E r | x> -1\2} b)B={x E r | 3< x<6} c)C=}x E r| 0< x<4 ou 2 d) D={ x E r | -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) .

∆red ≅ ∆ by rule will give brainiest if possible

What is the total area of the figure?
