Use the bip branch-and-bound algorithm presented in sec. 12.6 to solve the following problem interactively: maximize z = 2x1-x2 + 5x3-3x4 + 4x5, subject to 3x1-2x2 + 7x3-5x4 + 4x5 s 6 x2 + 2x3-4x4 + 2xs0 and x is binary, for j-1, 2, . . , 5.

What is always true about a positive integer raised to a negative odd power?

Acoffee shop orders at most $3,500 worth of coffee and tea. the shop needs to make a profit of at least $1,900 on the order. the possible combinations of coffee and tea for this order are given by this system of inequalities, where c = pounds of coffee and t = pounds of tea: 6c + 13t ≤ 3,500 3.50c + 4t ≥ 1,900 which graph's shaded region represents the possible combinations of coffee and tea for this order?
