Benchmark 2 REVIEW Math Flashcard part 3

Front

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 not equal to the other.

Front

How do you represent the opposite of a number on a number line?

Back

The opposite of a number is found by changing its sign. For example, the opposite of 5 is -5.

Front

What are the four quadrants of a coordinate plane?

Back

The four quadrants are: Quadrant I (x > 0, y > 0), Quadrant II (x < 0, y > 0), Quadrant III (x < 0, y < 0), Quadrant IV (x > 0, y < 0).

Front

How do you determine the fastest runner based on distance and time?

Back

To determine the fastest runner, calculate the speed (distance/time) for each run and compare the speeds.

Front

What is the order of operations in mathematics?

Back

The order of operations is Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right), often remembered by the acronym PEMDAS.

Front

What does it mean for a point to be located 5 units to the left on a graph?

Back

It means to subtract 5 from the x-coordinate of the point's location.

Front

What is the value of an expression?

Back

The value of an expression is the result you get after performing all the operations in the expression.

Front

What is a coordinate point?

Back

A coordinate point is a pair of numbers (x, y) that defines a specific location on a coordinate plane.

Front

How do you solve an expression with parentheses?

Back

First, solve the operations inside the parentheses, then follow the order of operations for the rest of the expression.

Front

What is a number line?

Back

A number line is a straight line with numbers placed at equal intervals along its length, used to represent numbers visually.
