Determine the number of slack variables and name them. Then use the slack variables to convert each constraint into a linear equation CHILD How many and which slack variables should be assigned? OA. There are five slack variables named X1, X2, 51, 52, 53 OB. There are three slack variables named X1, X2,5 OC. There are two slack variables named S, 52 OD. There are three slack variables named s, S2, S3 Assume the first equation using a slack variable is 9x,-X2+51 132 What is the second oquation after the slack variable is introduced? OA 13x, 6x2 +5, 226 OB. 13x+6x2 +$2=226 OC. 13x+6x+5+$ =226 What is the third equation after the slack variable is introduced? OA. 11x1 + x2 +52=345 OB. 11x+x+5, +52=345 Maximize: 25x, +3x2 subject to 9x1-2132 13x+6x2226 11x+345 with x20x20
