Answer 1

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.

Answer 2

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
