The point A (-7, 5) is reflected over the line x = -5, and then is reflected over the line x = 2. What are the coordinates of A'? (7, 19) (10, 5) (7, 5) (10, 19) Question #45 MultipleChoice The vertices of an isosceles triangle are A(3, 6), B(7, 2), and C(4, 3). What is the equation of the triangle's line of symmetry? y = x + 1 y = x - 1 y = x y = -x + 1 Question #46 MultipleChoice The area of a circle is 16π cm2. What is the circle's circumference? 2π cm 4π cm 8π cm 16π cm Question #47 MultipleChoice If AC = 20, AE = 25, and AB = 5, what is the length of ? 4 5 6 3 Question #48 MultipleChoice A square pyramid is 6 feet on each side. The height of the pyramid is 4 feet. What is the total area of the pyramid? 60 ft2 156 ft2 96 ft2 120 ft2 Question #49 MultipleSelect A'B'C'D' is the image of ABCD. What transformation(s) would result in this image? ABCD is reflected over the line y = x. ABCD is dilated about the origin with a scale factor of -1. ABCD is reflected across the y-axis and then the x-axis. ABCD is rotated 180° around the origin. Question #50 MultipleChoice A circle has a diameter with endpoints (-8, 2) and (-2, 6). What is the equation of the circle? r2 = (x - 3)2 + (y + 4)2 r2 = (x - 5)2 + (y + 4)2 r2 = (x + 5)2 + (y - 4)2 r2 = (x + 3)2 + (y - 4)2
