Algebra C&C Unit 3 Vocab Flashcard

Front

What is an explicit formula?

Back

Expresses the nth term of a sequence in terms of n.

Front

What is the definition for Solution Set?

Back

The set of two or more linear inequalities involving the same variables x and y.

Front

What is the definition for Linear Inequality?

Back

A mathematical expression in which two expressions are compared using the inequality symbol. Almost the same as a linear equation, except the equals sign is replaced with an inequality.

Front

What is the definition for Inequality?

Back

The relationship between two values showing if one is less than, greater than, or simply not equal to another value. (<, >, ≤ or ≥)

Front

What is an Arithmetic Sequence?

Back

A sequence where each term increases by adding/subtracting some constant k. This is in contrast to a geometric sequence where each term increases by dividing/multiplying some constant k.

Front

What is a Geometric Sequence?

Back

A sequence where each term increases by multiplication or division.

Front

What is a Linear Equation?

Back

A function that represents a straight line on the coordinate plane.

Front

What does it mean for a sequence to be recursive?

Back

Defines the terms in a sequence by relating each term to the ones before it.

Front

What is the difference between a linear equation and a linear inequality?

Back

A linear equation uses an equals sign, while a linear inequality uses inequality symbols (<, >, ≤, ≥).

Front

What is the slope of a line?

Back

The ratio of the rise (change in y) to the run (change in x) between two points on a line.
