The equation is solved. Describe the property used in each solution. Negative two-thirds a = 8. Negative two-thirds a (negative three-halves) = 8 (negative three-halves). a = –12 Negative two-thirds a divided by negative two-thirds = 8 divided by negative two-thirds. a = –12

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
