What are the coordinates of the vertices of D(3, A) (△ABC) for A(0, 4), B(–2, 5), and C(3, 7)? A. A′(0, 12), B′(−6, 15), C′(9, 21) B. A′(0, 15), B′(−6, 18), C′(9, 24) C. A′(0, 9), B′(−6, 12), C′(9, 18) D. A′(0, 4), B′(−6, 7), C′(9, 13)

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 an inequality for this description. - one fourth of the opposite of the difference of five and a number is less than twenty.
