Which of the problems below would require solving the following equations (after one divides out a couple constants): 2 = AT 3 = Ay 12 + 12- 13= 0 (a) Minimize z = 1 + y subject to a2 +2 = -13 (h) Minimize z = Ax + 6y subject to 2 + yz = 13 (a) Minimize z = ry subject to 12 + y2 = -13 (d) Minimize z = ry - y subject to 4x2 + 4y? = 13 (e) Minimize z - 212 - 3y subject to ? + 12 = 13
