The system of inequalities are $\"\"$ , $\"\"$ and $\"\"$ .

\

Graph:

\

Graph the inequalities $\"\"$ , $\"\"$ and $\"\"$ :

\

$\"\"$

\

Observe the graph:

\

The region shaded in pink color is the required solution set.

\

$\"\"$

\

Test the solution at point $\"\"$ .

\

Case (i):

\

$\"\"$ (First equation)

\

$\"\"$ (Substitute $\"\"$ )

\

$\"\"$ (Multiply)

\

$\"\"$ (Subtract)

\

Case (ii):

\

$\"\"$ (Second equation)

\

$\"\"$ (Substitute $\"\"$ )

\

$\"\"$ (Multiply)

\

$\"\"$ (Subtract)

\

Case (iii):

\

$\"\"$ (Third equation)

\

$\"\"$ (Substitute $\"\"$ )

\

$\"\"$ (Multiply)

\

$\"\"$ (Add)

\

Therefore, the region shaded contains the point $\"\"$ .
