Solve the following system of inequalities graphically:
Q12.
Graphical representation of is given in graph below.
For ,
The solution to this inequality is region above the line including points on this line because points on line also satisfy the inequality.
For ,
The solution to this inequality is region above the line including points on this line because points on line also satisfy the inequality.
For
The solution to this inequality is region right hand side of the line including points on this line because points on line also satisfy the inequality.
For
The solution to this inequality is region above the line including points on this line because points on line also satisfy the inequality.
Hence, solution to these linear inequalities is shaded region as shown in figure including points on the respective lines.
This can be represented as follows:
