Question

How is a constant term different

than a variable term for an expression that
represents a real-world situation?

Answer 1

Explanation:

A constant term in an expression is a term that has a fixed value and does not change, while a variable term is a term that can take on different values. For example, in the expression 5x + 2, the 2 is a constant term because it is always 2, while x is a variable term that can take on different values.

In a real-world situation, a constant term represents a quantity that does not change. For example, if we were to write an expression to represent the cost of a product, the constant term would be the fixed cost of the product that does not change. On the other hand, a variable term represents a quantity that is subject to change. For example, in the same scenario, the variable term would represent the quantity of the product being bought, which can change.

In summary, a constant term represents a fixed value that does not change, while a variable term represents a value that is subject to change in a real-world situation.

Answer 2

The difference between constant and variable is that, while the first, as we have already said, remains fixed within a formula, the variable can assume different values.
