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.

RadioShack sells Samsung and Lenovo tablets. When five Samsung tablets and eight Lenovo tablets are sold, RadioShack makes a profit of more than $1,920.00. The total cost of purchasing a Samsung and a Lenovo tablet cannot exceed $375.00. The total revenue made from the sale of nine Lenovo tablets and two Samsung is no more than $2,610. At no point in time, RadioShack's stock on either tablet will fall below 5 units. a. Derive five (5) linear inequalities to represent the above information. b. Using the same Cartesian Plane to represent each of the above linear inequalities from part a. above, solve the system of linear inequalities. Ensure that all work is clearly stated. c. Hence, label the solution from part b. above with a capital S.
