Please solve the following problem

Consider the following example Maximize z = 5x1 + 7x2 subject to 2x1 + 2x2 0 1 The line that represents the 1st constraint is: * 4 points 25 20 -15 -10 5 0 10 15 20 25 30 35 The "Green" line The "Blue" line The "Red" line None of the above 2 The line that represents the 2nd constraint is: * 4 points 20 15 10 5 0 10 15 20 25 30 35 40 45 The "Blue" line The "Green" line The "Red" line None of the above * The line that represents the 3rd constraint is: 4 points 3 The line that represents the 3rd constraint is: * 4 points 20 15 10 5 5 0 10 15 20 25 30 35 40 45 . The "Green" line O The "Blue" line O The "Red" line None of the above 4 * After shading to constraint lines, the feasible space is 4 points 25 20 -15 10 5 0 10 15 20 25 30 35 The "Pink" area The "Orange" area The "Yellow" area None of the answers. The "Green" area The value of "X1" at the optimum is: * 5 4 points None of the answers. 12 10.5 1.5 0 6 The value of "x2" at the optimum is: * 4 points 10.5 None of the answers. 1.5 0 12 7 The value of "z" at the optimum is: * 4 points 18 48 None of the answers. 84 81 8 Reverse the 2nd constraint. The new feasible space is * 4 points 25 20 -15 10 5 0 10 15 20 25 30 35 The "Yellow" area The "Pink" area The "Orange" area The "Green" area None of the answers. 9 The new values of X1 & X2 respectively are 4 points 0 & 12 1.5 & 10.5 10.5 & 1.05 12 &0 O None of the answers. 10 The new "z" value is * 4 points 81 84 48 18 None of the answers
