1)

\

The possible solution of the inequality is $\"\"$

\

Observe the graph,

\

The inequality is $\"\"$ the solution does not exist because the point is not shaded region.

\

Hence the inequality is not satisfied.

\

False.

\

\

2)

\

The possible solution of the inequality is $\"\"$

\

Observe the graph,

\

The inequality is $\"\"$ the solution is exist because the point is shaded region.

\

Hence the inequality is satisfied.

\

True.

\

\

3)

\

The possible solution of the inequality is $\"\"$

\

Observe the graph,

\

The inequality is $\"\"$ the solution is exist because the point is shaded region.

\

Hence the inequality is satisfied.

\

True.

\

4)

\

Find the system of equations.

\

Observe the graph,

\

The lines are solid then represents symbol is $\"\"$

\

The shaded region of the lines is shown

\

$\"\"$ is shaded region below the $\"\"$ axis at $\"\"$

\

Since, $\"\"$

\

$\"\"$ is shaded region above the $\"\"$ axis at $\"\"$

\

Since, $\"\"$

\

The system of equations

\

$\"\"$

\

5)

\

Find the system of equations.

\

Observe the graph,

\

The lines are doted lines then represents symbol is $\"\"$

\

The lines are solid then represents symbol is $\"\"$

\

The shaded region of the lines is shown

\

$\"\"$ is shaded region is above the $\"\"$ axis at $\"\"$ and represent doted line.

\

Since, $\"\"$

\

$\"\"$ is shaded region is below the $\"\"$ axis at $\"\"$ and represent solid line.

\

Since, $\"\"$

\

The system of equations

\
