What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions and shows that one is greater than, less than, or equal to the other. For example, c ≤ 15 means that the cost of lunch (c) is less than or equal to $15.

How do you represent a maximum spending limit using an inequality?

Back

If Ms. Rodgers can spend a maximum of $15, it can be represented as c ≤ 15, where c is the cost of her lunch.

Front

What are the coordinates of a point in Quadrant III?

Back

In Quadrant III, both the x-coordinate and y-coordinate are negative. For example, (-3, -1) is a point in Quadrant III.

Front

How do you calculate the total cost of multiple pounds of an item?

Back

To find the total cost, multiply the cost per pound by the number of pounds. For example, if cherries cost $2.75 per pound and Hannah bought 2.5 pounds, the total cost is 2.75 * 2.5 = $6.875.

Front

What is the percentage of time played if a player plays 65% of a game?

Back

If a quarterback plays 65% of a 60-minute game, the time played is calculated as 0.65 * 60 = 39 minutes.

Front

What does the ordered pair (2, -5.5) represent on a coordinate grid?

Back

The ordered pair (2, -5.5) represents a point located 2 units to the right of the origin and 5.5 units down on the coordinate grid.

Front

What is the formula for calculating the cost of an item based on weight?

Back

The formula is: Total Cost = Cost per Pound * Weight in Pounds.

Front

What does it mean for a point to lie in the interior of a triangle?

Back

A point lies in the interior of a triangle if it is inside the triangle and not on any of its sides.

Front

How do you determine if a point is in a specific quadrant of the coordinate plane?

Back

To determine the quadrant, check the signs of the x and y coordinates: Quadrant I (positive, positive), Quadrant II (negative, positive), Quadrant III (negative, negative), Quadrant IV (positive, negative).

Front

What is the significance of the maximum value in an inequality?

Back

The maximum value in an inequality indicates the highest limit that a variable can reach without exceeding a certain condition.
