The S-Cargo shipping company calculates shipping charges using the linear model, y = 2.72x, where y is the cost in dollars and x is the weight of the package in pounds (1 ≤ x ≤ 9). Use the linear model to compute the weight of a package with a shipping cost of $21.76. Round to the nearest hundredth of a pound, if necessary.
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.
