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.
What else can I help you with?
Which points are solutions to the system of inequalities?
To determine which points are solutions to a system of inequalities, you need to assess whether each point satisfies all the inequalities in the system. This involves substituting the coordinates of each point into the inequalities and checking if the results hold true. A point is considered a solution if it makes all the inequalities true simultaneously. Graphically, solutions can be found in the region where the shaded areas of the inequalities overlap.
What is the set of two or more inequalities?
A set of two or more inequalities is known as a system of inequalities. This system consists of multiple inequalities that involve the same variables and can be solved simultaneously to find a range of values that satisfy all conditions. Solutions to a system of inequalities are often represented graphically, where the feasible region indicates all possible solutions that meet all the inequalities. Such systems are commonly used in linear programming and optimization problems.
How would you know if the solutions you found from the graphs of linear inequalities in a system are true?
To verify the solutions of a system of linear inequalities from a graph, check if the points satisfy all the inequalities in the system. You can do this by substituting the coordinates of each point into the original inequalities to see if they hold true. Additionally, ensure that the points lie within the shaded region of the graph, which represents the solution set. If both conditions are met, the solutions are confirmed to be true.
How many solutions are there for a system of two quadratic inequalities?
The number of solutions for a system of two quadratic inequalities can vary widely, depending on the specific inequalities involved. They may have no solutions, a finite number of solutions, or infinitely many solutions. Graphically, the solutions correspond to the regions where the corresponding quadratic curves intersect and how they relate to each inequality. Therefore, analyzing each inequality's graph is crucial to determining the solution set.
How do you know which region of the graph of a system of linear inequalities contains the solutions?
If the lines intersect, then the intersection point is the solution of the system. If the lines coincide, then there are infinite number of the solutions for the system. If the lines are parallel, there is no solution for the system.

How do you know if a system has one solution?
If the equations or inequalities have the same slope, they have no solution or infinite solutions. If the equations/inequalities have different slopes, the system has only one solution.
What is the definition of equivalent inequalities?
The definition of equivalent inequalities: inequalities that have the same set of solutions
How is the solution in a system of inequalities determine?
An inequality determines a region of space in which the solutions for that particular inequality. For a system of inequalities, these regions may overlap. The solution set is any point in the overlap. If the regions do not overlap then there is no solution to the system.
How do you know which region of the graph of a system of linear inequalities contains the solutions?
If the lines intersect, then the intersection point is the solution of the system. If the lines coincide, then there are infinite number of the solutions for the system. If the lines are parallel, there is no solution for the system.
Can every systems of inequalities has a solution?
Not every system of inequalities has a solution. A system of inequalities can be inconsistent, meaning that there are no values that satisfy all inequalities simultaneously. For example, the inequalities (x < 1) and (x > 2) cannot be satisfied at the same time, resulting in no solution. However, many systems do have solutions, which can be represented as a feasible region on a graph.
How do you solve questions that say which graph best represents the system of inequalities?
The solution to a system of inequalities is where the solutions to each of the individual inequalities intersect. When given a set of graphs look for the one which most closely represents the intersection, this one will contain the most of the solution to the the system but the least extra.
Do solutions to systems of linear inequalities satisfy both inequalities?
Yes.
What points are solutions to the system of inequalities shown below y6x 7 y6x 9?
To determine the points that are solutions to the system of inequalities (y \leq 6x + 7) and (y \geq 6x + 9), we need to analyze the area between the two lines represented by these inequalities. The first inequality represents a region below the line (y = 6x + 7), while the second represents the region above the line (y = 6x + 9). Since the two lines are parallel, there are no points that satisfy both inequalities simultaneously; thus, there are no solutions to the system.
