Part A: Translate the situation into an algebraic equation: Ann has 5 brand new music CD’s, which is 3 less than twice the amount that Bob x has. Part B: For the correct equation, find the value of x (the number of brand new CD's Bob has).

Astudent draws two parabolas both parabolas cross the x axis at (-4,0) and (6,0) the y intercept of the first parabolas 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
