Algebraic Solutions and Graphical Interpretations of Inequalities

A farmer has a rectangular field and wants to plant two types of crops. The area for crop A is represented by the inequality x^2 + y^2 ≤ 100, while the area for crop B is represented by the inequality y ≥ x + 10. Graph the system of inequalities and determine the feasible region for planting both crops.

• The feasible region is the area inside the circle x^2 + y^2 ≤ 100 only.

• The feasible region is the area above the line y = x + 10 that lies outside the circle x^2 + y^2 ≤ 100.

• The feasible region is the area above the line y = x + 10 that lies within the circle x^2 + y^2 ≤ 100.

• The feasible region is the area below the line y = x + 10 that lies outside the circle x^2 + y^2 ≤ 100.

A company produces two products, P and Q. The profit from product P is represented by the inequality 3x + 2y ≤ 60, and the production cost for product Q is represented by the inequality y ≤ -x^2 + 20. Solve the inequalities algebraically and interpret the solution graphically to find the maximum profit region.

• The maximum profit region is determined solely by the profit from product P.

• The maximum profit region is defined by the intersection points of the line and the parabola, which can be calculated to find the optimal production levels for products P and Q.

• The inequalities indicate that product Q cannot be produced at all.

• The maximum profit region is a single point where x and y are both zero.
