Decision variables are
Correct answer: C. nonnegative constraints
- A. negative constraints
- B. positive constraints
- C. nonnegative constraints
- D. None
Explanation
Decision variables are typically subject to nonnegative constraints. This means that the values of decision variables must be greater than or equal to zero. Nonnegative constraints are commonly used in optimization and linear programming problems to ensure that decision variables represent quantities that cannot be negative.

About Linear Equations
Linear equations contain variables only to the first power and produce straight-line relationships when represented graphically. Problems involve solving equations with brackets, fractions, and variables on both sides, forming equations from statements, and handling simultaneous linear equations, which differ from quadratic equations by having no squared variable.
