Suppose you have a 42-inch TV that is 57 centimeters tall by 96 centimeters wide. You want to upgrade to the 60-inch version of that TV but worry that it might be too tall. The height and width of the 42-inch and 60-inch TVs are proportional. If you know the width of the 60-inch TV is 137 centimeters, which proportion could you use to calculate the height (also in centimeters) of the 60-inch TV? Use h for height. a. b. c. d.
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.
