A landscaping company is hired to mow the grass for several large properties. The total area of the properties combined is 1,350 acres. The rate at which one person can mow is as follows: Ŷ = -1.8X + 1350 Where X is the number of hours and Ŷ represents the number of acres left to mow. a. How many acres will be left to mow after 40 hours of work by one person? b. How many acres will be left to mow after 100 hours of work by one person? (now you see why you need a large crew to mow many acres!)
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.
