Amath class is having a discussion on how to determine if the expressions 4x-x+5 and 8-3x-3 are equivalent using substitution. the class has suggested four different methods. which describes the correct method? 1) both expressions should be evaluated with one value. if the final values of the expressions are both positive, then the two expressions must be equivalent. 2)both expressions should be evaluated with one value. if the final values of the expressions are the same, then the two expressions must be equivalent. 3)both expressions should be evaluated with two different values. if for each substituted value, the final values of the expressions are positive, then the two expressions must be equivalent. 4)both expressions should be evaluated with two different values. if for each substituted value, the final values of the expressions are the same, then the two expressions must be equivalent.

Identify the converse of the following conditional: if a point is in the first quadrant, then its coordinates are positive. if the coordinates of a point are not positive, then the point is not in the first quadrant. if the coordinates of a point are positive, then the point is in the first quadrant. if a point is in the first quadrant, then its coordinates are positive. if a point is not in the first quadrant, then the coordinates of the point are not positive.
