Front

What is a constant?

Back

A constant is a fixed value that does not change. For example, in the expression 3x + 5, the number 5 is a constant.

Front

What is a variable?

Back

A variable is a symbol used to represent an unknown value. For example, in the expression 2x + 3, 'x' is a variable.

Front

What is a coefficient?

Back

A coefficient is a number that is multiplied by a variable in an expression. For example, in 4x, the number 4 is the coefficient.

Front

What is the role of a constant in an equation?

Back

Constants provide fixed values that help define the equation's behavior.

Front

What is the role of a variable in an equation?

Back

Variables allow for the representation of unknown values and can change within the equation.

Front

What happens to the value of an expression if you change the variable?

Back

Changing the variable will change the value of the expression, depending on the new value assigned to the variable.

Front

In the term 3x^2, what is the coefficient?

Back

3 is the coefficient in the term 3x^2.
