Graphing systems of linear inequalities worksheet

The definition of a system of linear inequalities is very similar to the definition of a system of linear equations. Two or more linear inequalities grouped together form a system of linear inequalities. A system of linear inequalities looks like a system of linear equations, but it has inequalities instead of equations. A system of two linear inequalities is shown below. To solve a system of linear inequalities, we will find values of the variables that are solutions to both inequalities. We solve the system by using the graphs of each inequality and show the solution as a graph. We will find the region on the plane that contains all ordered pairs x,y x,y that make both inequalities true. Solutions of a system of linear inequalities are the values of the variables that make all the inequalities true. The solution of a system of linear inequalities is shown as a shaded region in the x-y coordinate system that includes all the points whose ordered pairs make the inequalities true. To determine if an ordered pair is a solution to a system of two inequalities, we substitute the values of the variables into each inequality. If the ordered pair makes both inequalities true, it is a solution to the system. Determine whether the ordered pair is a solution to the system. The ordered pair 3,1 made one inequality true, but the other one false.

A system of inequalities is a set or type of two or more inequalities in one or more variables form. Systems of inequalities are used when a problem requires a different range of solutions, and there is one more additional constraint on those solutions. Just have the idea with the example. Jack is the manager of a well-established textile factory. His workers have a total of person-hours this week for him to allocate. The target is settled as every ten shirts will take 2 hours to produce, and every ten pairs of pants will take 3 hours to produce. Jack has a set target to manufacture at least 30 shirts and 20 pairs of pants this week. How will Jack allocate his person-hours, and how will his production get ready on time? This is where the system of inequalities will do the job.
