At a bargain store, Jamal bought 2 items that each cost the same amount. Isaiah bought 3 items that each cost the same amount, but each was $2.25 less than the items that Jamal bought. Both Jamal and Isaiah paid
the same amount of money. What was the individual cost of each person's items? (5 points)
(a) Write an equation. Let x represent the cost of one of Jamal's items. Your equation should have an x
term on both sides. (2 points)
(b) Solve the equation and identify the costs. SHOW YOUR WORK. (3 points)
(c) Check your solution. SHOW YOUR WORK. (1 bonus point).

Suppose you want to transform the graph of the function y=tan(x+pi/4)-1 into the graph of the function y=-tan(x+pi/2)+1 which transformations should you perform. a) reflect the graph of the first function across the x-axis, translate it pi/4 units to the left, and translate it 2 units up. b) reflect the graph of the first function across the x-axis, translate it pi/4 units to the right, and translate it 2 units up. c) reflect the graph of the first function across the line y = -1, translate it pi/4 units to the left, and translate it 2 units up. d) reflect the graph of the first function across the line y = -1, translate it pi/4 units to the right, and translate it 2 units up.
