The value of A is implied in the information. What is it? e. Substitute the value for A and solve the two equations with S and C. to find their value. f. How many of each were sold?
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.
