How do you isolate a variable in an inequality?

Back

To isolate a variable in an inequality, perform inverse operations on both sides of the inequality, similar to solving an equation, while remembering to reverse the inequality sign when multiplying or dividing by a negative number.

How do you graph an inequality on a number line?

Back

To graph an inequality on a number line, use an open circle for '>' or '<' and a closed circle for '≥' or '≤'. Shade the line in the direction of the inequality.

What is the first step in solving the inequality 12x + 400 < 1200?

Back

The first step is to subtract 400 from both sides of the inequality, resulting in 12x < 800.

What is the solution to the inequality -3 - 6(4x + 6) > -111?

Back

First, simplify to get -3 - 24x - 36 > -111, then combine like terms to find -24x > -72, and finally divide by -24, reversing the inequality to get x < 3.
