Use slack variables to convert the constraints into linear equations.Maximizex + 2y + 3zsubject to:x + 4y + 8z ? 40 7x + y + 4z ? 50with:x ? 0, y ? 0, z ? 0

A. x + 4y + 8z = u - 40 7x + y +4z = v - 50 -x - 2y - 3z + M = 0 Maximize M given that x ? 0, y ? 0, z ? 0, u ? 0, v ? 0 B. x + 4y + 8z = u + 40 7x + y +4z = v + 50 -x - 2y - 3z = M Maximize M given that x ? 0, y ? 0, z ? 0, u ? 0, v ? 0 C. x + 4y + 8z + u = 40 7x + y + 4z + v = 50 -x - 2y - 3z + M = 0 Maximize M given that x ? 0, y ? 0, z ? 0, u ? 0, v ? 0 D. x + 4y + 8z + u = 40 7x + y + 4z + v = 50 x + 2y + 3z + M = 0 Maximize M given that x ? 0, y ? 0, z ? 0, u ? 0, v ? 0

Find the standard form, degree, and leading term for the polynomial function. f(x) = 2 + 7x - 9x3

A. Standard form: f(x) = -9x3 + 7x + 2, Degree: 3, leading term: -9 B. Standard form: f(x) = 9x3 + 7x + 2, Degree: 3, leading term: x3 C. Standard form: f(x) = -9x3 + 7x + 2, Degree: 3, leading term: -9x3 D. Standard form: f(x) = 2 + 7x - 9x3, Degree: 0, leading term: 2
