Study Notes
Algebra Concepts and Definitions
- FOIL: Method to multiply two binomials; stands for first, outer, inner, last terms.
- Point-Slope Form: Equation of a line expressed as (y - y_1 = m(x - x_1)), where (m) is the slope and ((x_1, y_1)) is a point on the line.
- Absolute Value: Indicates the distance a number is from zero on a number line, always non-negative.
- Real Numbers: The set that includes all rational (e.g., integers, fractions) and irrational numbers (e.g., square roots of non-perfect squares).
- Rational Numbers: Numbers that can be represented as (a/b), where (a) and (b) are integers, and (b \neq 0); in decimal form, they either terminate or repeat.
- Irrational Numbers: Numbers that cannot be expressed as the quotient of two integers; their decimal forms neither terminate nor repeat.
- Symbol of Conclusion: Symbol that groups numbers, variables, and operations into a single term.
- Square Roots: A number that, when multiplied by itself, yields a given product.
- Probability: A measure reflecting how likely an event occurs, typically expressed as a percentage.
- Distributive Property: A property that allows the multiplication of a term across a sum or difference within parentheses to simplify expressions.
- Variable Expressions: Algebraic expressions that include letters representing numbers.
- Translating Algebraic Expressions: The process of converting words into symbolic expressions to enhance understanding.
- Combining Like Terms: The process of adding or subtracting terms that have identical variables or exponents.
- One-Step Equations: Equations that can be solved in a single operation.
- Graphing on a Coordinate Plane: The process of determining the orientation of a line (horizontal or vertical) and plotting it accurately.
- Two-Step Equations: Equations requiring two steps to isolate the variable and find the solution.
- Decimal Equations: Algebraic equations that include decimal numbers; converting fractions to decimals for easier solving is a common strategy.
- Relations: Describes how two or more mathematical concepts interact or are connected.
- Functions: Describe the role or output of a number in an algebraic expression.
- Multi-Step Equations: Equations that require three or more operations to solve for the variable.
- Misleading Representations of Data: Data that is distorted and does not accurately reflect true facts or statistics.
- Solving Equations with Variables on Both Sides: Requires elimination methods to isolate variables and resolve the equation.
- Literal Equations: Equations where variables symbolize known quantities.
- Graphic Function: A collection of ordered pairs representing a function visually.
- Rates: Measurements that express a quantity in relation to another quantity.
- Ratios: A quantitative comparison between two amounts reflecting how many times one value contains another.
- Proportions: A statement that two ratios are equal, expressing a comparative relation to a whole.
- Arithmetic Sequences: A sequence of numbers with a consistent difference between consecutive terms.
- Intercepts: Points where a line crosses the axes, integral to understanding linear equations.
- Scientific Notation: A method to express large or small numbers by using powers of ten, simplifying mathematical computations.
- Power Property of Exponents: When multiplying like bases, sum the exponents.
- Percent Problems: Involves expressing quantities as a fraction of 100.
- Rational Expression: A fraction where both the numerator and/or denominator are polynomials.
- Percent Change: The rate of increase or decrease represented as a percentage of the original amount.
- Measure of Central Tendency: A statistic that represents the center of a data set, typically including the mean, median, and mode.
- Slope-Intercept Form: The equation of a line written as (y = mx + b), where (m) is the slope and (b) is the y-intercept.
- Polynomials: Expressions consisting of multiple terms combined using addition, subtraction, and multiplication.
- Linear Equation: An equation involving two variables that results in a straight line when plotted on a graph.
- Direct Variation: A relationship where two variables change proportionally, typically expressed as (y = kx) where (k) is a constant.
