An equation that expresses a relationship between two or more variables, such as H = 9/10(220 - a), is called a/an______ . The process of finding suchequations to describe real-world phenomena is called mathematical_______ . Such equations, together with the meaning assigned to the variables, are called mathematical_________ .
Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
