Is the given number a solution of the inequality? $$2 x+4 \leq 3 x-3 ; 5$$
Decide whether the given point lies on the line. Justify your answer both algebraically and graphically. $$-4 x-3 y=-8 ;(-4,2)$$
CRITICAL THINKING Consider the equation \(6 x+8 y=k .\) What numbers could replace \(k\) so that the \(x\) -intercept and the \(y\) -intercept are both integers? Explain.
You start a daily flower club and charge \(\$ 10\) to join and \(\$ .50\) per day. Every day each member of the club gets a fresh flower. Let \(n\) represent the number of club members and let \(I\) represent your income for four weeks. A model for the situation is \(I=[10+4 \cdot 7(0.5)] n .\) Write an input-output table that shows your income for \(2,4,6,8,\) and 10 club members.
Use the following information. Your school drama club is putting on a play next month. By selling tickets for the play, the club hopes to raise \(\$ 600\) for the drama fund for new costumes, scripts, and scenery for future plays. Let \(x\) represent the number of adult tickets they sell at \(\$ 8\) each, and let \(y\) represent the number of student tickets they sell at \(\$ 5\) each. What is the \(x\) -intercept? What does it represent in this situation?
