The variables used in the system of linear inequalities are
Correct answer: B. non negative
- A. negative
- B. non negative
- C. feasible region
- D. None
Explanation
In the context of linear inequalities and optimization problems, the variables used typically represent quantities that cannot be negative. These variables are often constrained to be nonnegative, meaning their values must be zero or positive. This restriction is common in many practical scenarios, such as quantities representing quantities of goods, resources, or decision choices, where negative values do not make sense.

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.
