Homework Answers

Answer #1

All linear program can be converted to standard form. Process is as follows-

(1) Negative variables can be converted to non negative by replacing it as -(-x) = - y where y=-x which is non negative.

(2) A constraint with negative RHS can be multiplied by -1 to get positive RHS.

(3) To make an inequalities equality we can add or subtract a slack variable.

(4) Unrestricted variables can be transformed to restricted variables by writing it into difference of two new non-negative variables.

Hence a Linear Program can always be converted into standard one.

The law of conservation of energy states that energy can be converted from one form to another but cannot be created or destroyed. Therefore, the amount of energy in the universe is constant. In your initial post to the discussion, respond to the following prompts: What do you think would happen if energy were not conserved? Think of (and share) two scenarios in which our lives would be drastically altered if this law of conservation was not in place. At...
