Logan solved the system of equations using the elimination method. 3x – 12y = 9 -2x – 2y = -6 His solution was (3,0). Is he correct? If yes, describe the steps he took to find the solution. If no, explain what he did incorrectly and what he needs to do to correct his mistake.

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
