Coefficient, Constant, Variable

Front

What is a coefficient?

Back

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

Front

What is a constant?

Back

A constant is a fixed value that does not change. For example, in the expression 3x + 4, the number 4 is a constant.

Front

What is a variable?

Back

A variable is a symbol used to represent an unknown value. Common variables include x, y, and z.

Front

What is a term in an algebraic expression?

Back

A term is a single mathematical expression that can be a number, a variable, or a combination of both, such as 3x or 5.

Front

Identify the coefficient in the expression 7y + 2.

Back

The coefficient is 7.

Front

Identify the constant in the expression 4x - 9.

Back

The constant is -9.

Front

Identify the variable in the expression 3a + 5b.

Back

The variables are a and b.

Front

What is the difference between a coefficient and a constant?

Back

A coefficient is a number that multiplies a variable, while a constant is a fixed number that does not change.

Front

In the expression 2x + 3y - 5, how many terms are there?

Back

There are three terms: 2x, 3y, and -5.

Front

What is the role of variables in algebraic expressions?

Back

Variables represent unknown values and allow us to create general formulas and equations.
