A slack variable is added to a constraint in order to create equality Is generally used in solving maximization or minimization problems subject to certain assumptions. The constraint 41+8220, when converted to an = constraint for use in the simplex algorithm, will be 41+8251=20 1. The constraint 3x1+2X250, when converted to an = constraint for use in the simplex aigorithm, will be: 3x1+2x2s1=503X1+2x2+s1=503X12X2+s1=50 None of them Any column or raw of a simplex table is called a Vector Key column Key Raw None of the above In maximization cases, function are assigned to the artificial variables as their coefficients in the objective +mm0 None of the above In simplex algorithm, which method is used to deal with the situation where an infeasible starting basic solution is given? Slack variable Simplex method big M method None of the above The variable added to the LHS of a less than or equal to constraint to convert it into equality is called variable. slack artificial surplus additional In simplex method, we add variables in the case of ' = ' Slack Variable Surplus Variable Artificial Variable None of the above In simplex, MOS occurs when objective function isn't parallel to a binding constraint
