Module 3 q2Please put answers in BOLD text. Thanks! Will upvote.

The following questions refer to a capital budgeting problem with six projects represented by 0-1 variables xq, X2, X3, 44, 45, and X (a) Write a constraint modeling a situation in which exactly three of the projects 1, 3, 5, and 6 must be undertaken. *1 + x3 + x3 + x6 = 2 X (b) Write a constraint modeling a situation in which, if projects 3 or 5 must be undertaken, then they must be undertaken simultaneously. x3 + x3 = (C) Write a constraint modeling a situation in which project 1 or 4 must be undertaken, but not both. x1 + x4 = 1 (d) Write constraints modeling a situation where project 4 cannot be undertaken unless projects 1 and 3 also are undertaken. (Enter your answer as a comma-separated list of equations and/or inequalities.) *4 5X1,44 3X3 (e) In addition to the requirement in part (d), assume that when projects 1 and 3 are undertaken, project 4 also must be undertaken. (Enter your answer as a comma-separated list of equations and/or inequalities.) *4 >xy +xz-1 X
