Evan made this toothpick pattern. He described the pattern with the equation \(t=5 n-3,\) where \(t\) is the number of toothpicks in Stage \(n .\) a. Explain how each part of the equation is related to the toothpick pattern. b. How many toothpicks would Evan need for Stage 10\(?\) For Stage 100\(?\) c. Evan used 122 toothpicks to make one stage of his pattern. Write and solve an equation to find the stage number. d. Is any stage of the pattern composed of 137 toothpicks? Why or why not? e. Is any stage of the pattern composed of 163 toothpicks? Why or why not? f. Evan has 250 toothpicks and wants to make the largest stage of the pattern he can. What is the largest stage he can make? Explain your answer.
Solve each equation or inequality. a. \(1-x=0\) b. \(1-x<0\) c. \(1-x>0\)
Wednesday nights are special at the video arcade: customers pay \(\$ 3.50\) to enter the arcade and then only \(\$ 0.25\) to play each game. Roberto brought \(\$ 7.50\) to the arcade and still had some money when he left. Write an inequality for this situation, using \(n\) to represent the number of games Roberto played.
When you draw a graph, you have to decide the range of values to show on each axis. Each exercise below gives an equation and a range of values for the \(x\) -axis. Use an inequality to describe the range of values you would show on the \(y\) -axis, and explain how you decided. (It may help to try drawing the graphs.) $$y=x^{2}+1 \text { when }-5 \leq x \leq 5$$
Write each equation in the form \(y=m x+b.\) $$-2 y=14 x+\frac{1}{2}(6 x+12)$$
