What set of reflections would carry parallelogram ABCD onto itself? (5 points) Parallelogram ABCD is shown. A is at negative 1, negative 2. B is at negative 2, negative 1. C is at negative 4, negative 1. D is at negative 3, negative 2. x-axis, y=x, x-axis, y=x y=x, x-axis, y=x, y-axis y-axis, x-axis, y-axis x-axis, y-axis, y-axis

Astudent draws two parabolas on graph paper. both parabolas cross the x-axis at (–4, 0) and (6, 0). the y-intercept of the first parabola is (0, –12). the y-intercept of the second parabola is (0, –24). what is the positive difference between the a values for the two functions that describe the parabolas? write your answer as a decimal rounded to the nearest tenth
