4.6 Parts of an Algebraic Expression Day 2

Front

What is a constant in an algebraic expression?

Back

A constant is a fixed value that does not change. For example, in the expression 4y + 2 + x, the constant is 2.

Front

Identify the variables in the expression: 6 + 7n - 3 + 2y

Back

The variables are n and y.

Front

What is a coefficient in an algebraic expression?

Back

A coefficient is a numerical factor that multiplies a variable. For example, in the expression 5y, the coefficient is 5.

Front

Identify the coefficient in the expression: n + 12

Back

The coefficient is 1, as it is understood that n has a coefficient of 1.

Front

What are the variables in the expression: 9m + 3n + 4?

Back

The variables are m and n.

Front

Identify the constant in the expression: 5y + 7n - 3

Back

The constant is -3.

Front

What is an algebraic expression?

Back

An algebraic expression is a combination of numbers, variables, and operations. For example, 4x + 5 is an algebraic expression.

Front

What does it mean for a variable to be in an expression?

Back

A variable represents an unknown value and can change. In the expression 3x + 2, x is the variable.

Front

How do you identify the terms in an algebraic expression?

Back

Terms are the parts of an expression separated by plus or minus signs. For example, in 4y + 2 + x, the terms are 4y, 2, and x.

Front

What is the difference between a term and a factor?

Back

A term is a single part of an expression, while a factor is a number or variable that multiplies another number or variable.
