Hi who wants some free points

Write the equation for the parabola that has x− intercepts (−2,0) and (4,0) and y− intercept (0,4).

Graph the line that represents a proportional relationship between d and t with the property that an increase of 33 units in t corresponds to an increase of 44 units in d. what is the unit rate of change of dd with respect to t? (that is, a change of 11 unit in t will correspond to a change of how many units in d? )

Which property was used to simplify the expression? 3c+9 +4c=3c+4c+9
