It represents the solution set.
A system of linear inequalities
A system of linear inequalities give you a set of answers that could work. In day to day lives we actually use linear inequalities all the time. We are given questions and problems where we search for a number of possible solutions.
yes it is possible for a system of two linear inequalities to have a single point as a solution.
When there is an ordered pair that satisfies both inequalities.
yes
Many problems in economics can be modelled by a system of linear equations: equalities r inequalities. Such systems are best solved using matrix algebra.
Not quite sure of the direction of the argument required.Any inequality can be made into an equality by using an auxiliary variable. For example,x + 2y < 3 is equivalent to x + 2y - a = 3 where a is some positive variable. [This method is used in linear programming.]Conversely, any equality can be written as a combination of two inequalities. For example,x + 2y = 3 is the same asx + 2y ≤ 3 and x + 2y ≥ 3
When the lines never intersect, usually when they are parallel.
the answer is true
Systems of inequalities in n variables with create an n-dimensional shape in n-dimensional space which is called the feasible region. Any point inside this region will be a solution to the system of inequalities; any point outside it will not. If all the inequalities are linear then the shape will be a convex polyhedron in n-space. If any are non-linear inequalities then the solution-space will be a complicated shape. As with a system of equations, with continuous variables, there need not be any solution but there can be one or infinitely many.
