Question

match the following variable constant coefficient a letter representing an unknown number a number multiplying a variable a number without a variable

Explanation:

To solve the matching, we use the definitions of each term:

• A variable is a letter (like \( x \), \( y \)) that represents an unknown number. So "variable" matches "a letter representing an unknown number".
• A constant is a number that has no variable associated with it (e.g., 5, -3). So "constant" matches "a number without a variable".
• A coefficient is a number that multiplies a variable (e.g., in \( 3x \), 3 is the coefficient of \( x \)). So "coefficient" matches "a number multiplying a variable".

Answer:

variable - a letter representing an unknown number
constant - a number without a variable
coefficient - a number multiplying a variable
