What are the order of operations? Correct Answer: The order of operations can be remembered as
PEMDAS: Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction.
When graphing straight lines what is the variable X called? Correct Answer: The Independent Variable
When graphing straight lines what is the variable Y called? Correct Answer: The Dependent Variable
A solution set Correct Answer: All the ordered pairs of real numbers that satisfy an equation consisting
of two variables such as x or y
A Point Correct Answer: A graph of an ordered pair
The horizontal line on a Cartesian plane Correct Answer: X axis
The Vertical line on a Cartesian plane Correct Answer: Y axis
Cartesian Plane Correct Answer: Defined by two perpendicular number lines: the horizontal x-axis and
the vertical y-axis.Using these axes, we can describe any point in the plane using an ordered pair of
numbers.
Power Rule for Exponents Correct Answer: (am)n=amn
To raise a power to a power, multiply the exponents.
Power Rule for Products Correct Answer: Power Rule for Products: (ab)n=anbn
To raise a product to a power, raise each factor to that power.
The Power Rule of Fractions Correct Answer: To raise a fraction to a power, raise the numerator and
denominator to that power.
Natural Numbers Correct Answer: 1,2,3,4, etc. No zero, Negatives, or fractions.
Whole Numbers Correct Answer: Natural numbers plus zero.
Integers Correct Answer: Whole numbers, natural numbers, and negative numbers.
Rational Numbers Correct Answer: Integers written as non-zero fractions, Terminating decimals,
negative fractions, and repeating decimals.
Irrational numbers Correct Answer: Infinate non-repeating decimals, including pie and some square
roots.
