The coordinates of the vertices of a triangle are (4, -3), (1, 1), and (4,3). The triangle is rotated clockwise about the origin. The coordinates of one vertex of the new image are (3, 4). Which could be the rotation? A It could only be clockwise 180°. B It could only be clockwise 90°. с It could only be clockwise 270º. D It could be either clockwise 90° or clockwise 270º.

Given the system of equations presented here: 2x + 4y = 14 4x + y = 20 which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? multiply the second equation by â’4 to get â’16x â’ 4y = â’80 multiply the second equation by â’1 to get â’4x â’ y = â’20 multiply the first equation by 2 to get 4x + 8y = 28 multiply the first equation by â’1 to get â’2x â’ 4y = â’14
