Solution any value that makes the open sentence true
Intersection Point the ordered pair that satisfies both functions at the same time
Solve an inequality to determine the values of the variable that make the inequality true
compound inequality an inequality that is formed by the union, "or," or the intersection, "and," of two simple inequalities
solution of a compound inequality in the form, a<x<b, where a and b are any real numbers, is the part or parts of the solutions that satisfy both of the inequalities
conjunction a compound inequality of the form a<x<b
disjunction a compound inequality of the form x<a or x>b
opposites two numbers that are equal distance, but are in different directions, from zero on the number line
absolute value its distance from zero on the number line
linear absolute value equation an equation of the form a +b|cx + d| + f = g, where a, b, c, d, f, and g are any real numbers
linear absolute value inequality an inequality of the form a +b|cx + d| + f < g, where a, b, c, d, f, and g are any real numbers
equivalent compound inequality when you separate an absolute value inequality into a compound inequality

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

• SPACEBAR - flip the current card
• LEFT ARROW - move card to the Don't know pile
• RIGHT ARROW - move card to Know pile
• BACKSPACE - undo the previous action

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
