At the end of the day, the change machine at a laundrette contained at least \(\$ 3.20\) and at most \(\$ 5.45\) in nickels, dimes, and quarters. There were 3 fewer dimes than twice the number of nickels and 2 more quarters than twice the number of nickels. What was the least possible number and the greatest possible number of nickels?
Solve each inequality using a graphing utility. Graph each of the three parts of the inequality separately in the same viewing rectangle. The solution set consists of all values of \(x\) for which the graph of the linear function in the middle lies between the graphs of the constant functions on the left and the right. $$2 \leq 4-x \leq 7$$
Explain how to graph \(x-2 y<4\)
Explain how to solve \(1<2 x+3<9\)
Will enable you to review graphing linear functions. In addition, they will help you prepare for the material covered in the next section. In each exercise, graph the linear function. $$f(x)=-\frac{2}{3} x \text { or } y=-\frac{2}{3} x(\text { Section } 3.4, \text { Example } 4)$$
