For each system, determine if it is in standard form.

(4 points) For each system, determine if it is in standard form. Maximize P = 5x1 + x2 subject to the constraints 8x1 + 10x1 - x 20 x2 9 7 0 A. Yes, in standard form. B. No, not in standard form. Maximize P = x1 + 7x2 + x3 subject to the constraints 4x1 2x + + x2 9x2 + - x3 X3 = 5 -9 6 x 20 x2 > 0 X3 > 0 A. Yes, in standard form. B. No, not in standard form. Maximize P = 2x1 + 8x2 + x3 subject to the constraints x1 + 3x2 + 6x3 x1 = > 6 0 A. Yes, in standard form. B. No, not in standard form. Maximize P= 10x1 + 9x2 subject to the constraints 3x1 x1 x120 + + x2 5 5 10x2 42 x2 > 0 A. Yes, in standard form. B. No, not in standard form. Maximize P = 2x1 + 10x2 + 2x3 subject to the constraints x1 - x2 + x3 x2 = 7 = 8 x120 x2 20x320 A. Yes, in standard form. B. No, not in standard form
