Solving One-step Inequalities

Inequalities Inequalities are similar to equations when solving. You can add, subtract, multiply or divide any amount to either side as long as you do it to both sides.

4 6 8 10 12 14 16 18 20 Solve x - 6 < 10 and graph the solution. The point 16 in not included. The circle is open. BACK

2 3 4 5 6 7 8 9 10 BACK

Which of the following is the graph of r < 1? -3 -2 -1 0 1 2 3 4 5 A B C C BACK

2 3 4 5 6 7 8 9 10 Write an inequality for the graph. Closed dot means the number 4 is included. x 4 BACK

-3 -2 -1 0 1 2 3 4 5 BACK

-9 -8 -7 -6 -5 -4 -3 -2 -1 BACK

-6 -5 -4 -3 -2 -1 0 1 2 BACK

When you multiply or divide each side of an inequality by a negative integer, you must reverse the order symbol. Warning!!! BACK

-6 -5 -4 -3 -2 -1 0 1 2 BACK

Do you change the sign if you multiply or divide by a positive number while solving? NO!!!! BACK

Do you change the sign? No Yes BACK
