Which inequality symbol means more than or above?

•  $>$  Is greater than

•  $\ge$  Is greater than or equal to

•  $<$  Is less than

•  $\le$  Is less than or equal to

Which inequality symbol means at most or no more than?

• $>$ Is greater than

• $\le$ Is less than or equal to

• $\ge$ Is greater than or equal to

• $<$ Is less than

Which inequality symbol means fewer than or below?

• $>$ Is greater than

• $\le$ Is less than or equal to

• $<$ Is less than

• $\ge$ Is greater than or equal to

Which inequality symbol means at least or no less than?

• $<$ Is less than

What is the first step in solving inequalities?

• Write down the original problem.

• Graph the inequality on a number line.

• Put an open circle on the graph.

• Write down the answer.

What is the second step in solving a one-step inequality?

• Write down the answer.

• Perform the inverse operation to isolate the variable.

• Graph the answer on a number line.

• Draw an arrow on the number line.

What is the third step when solving a one-step inequality?

• Write your answer in the form of x = some rational number.

• Draw a closed circle on the graph.

• Write your answer in the form of x $<,>,\le,\ or\ \ge$ some rational number.

• Just write the number that is your answer.

Once you've solved the inequality, what is your next step?

• Nothing, you're done.

• Put a circle on a number line.

• Graph the solution on a coordinate grid.

• Graph the solution on a number line.

When is the circle open on the graph of an inequality?

• When the inequality is either $<\ or>$ , because it does not include the solution itself.

• When the inequality is either $\le or\ge$ , because it includes the solution itself.

• When the arrow goes to the left.

• When the solution is negative.

When is the circle closed on the graph of an inequality?

• When the arrow goes to the right.

• When the inequality is either $\le or\ge$ , because it includes the solution itself.

• When the inequality is either $<or>$ , because it does not include the solution itself.

• When the solution is positive.
