The coordinate plane below represents a town. Points A through F are farms in the town. graph of coordinate plane. Point A is at negative 3, negative 4. Point B is at negative 4, 3. Point C is at 2, 2. Point D is at 1, negative 2. Point E is at 5, negative 4. Point F is at 3, 4. Part A: Using the graph above, create a system of inequalities that only contains points A and E in the overlapping shaded regions. Explain how the lines will be graphed and shaded on the coordinate grid above. (5 points) Part B: Explain how to verify that the points A and E are solutions to the system of inequalities created in Part A. (3 points) Part C: Chickens can only be raised in the area defined by y < −2x + 4. Explain how you can identify farms in which chickens can be raised. (2 points)

An anthropologist studies a woman's femur that was uncovered in Madagascar. To estimate the woman's height, he uses the equation h=60+2.5fh=60+2.5fh, equals, 60, plus, 2, point, 5, f, where hhh represents height in centimeters and fff represents length of the femur in centimeters. Which inequality best represents the lengths of the femur that would suggest the woman had a height greater than 160\,\text{cm}160cm160, space, c, m?

Adam and Edwin spend a certain amount of money from their money box each month to buy plants. The table shows the relationship between the amount of money (y) remaining in Adam's money box and the number of months (x): Function 1: Number of Months (x) Amount Remaining (dollars) (y) 1 90 2 83 3 76 4 69 The equation shows the relationship between the amount of money, y, remaining in Edwin's money box and the number of months, x: Function 2: y = –9x + 90 Which statement explains which function shows a greater rate of change? Function 2 shows a greater rate of change, because Edwin spends $90 each month and Adam spends $21 each month. Function 2 shows a greater rate of change, because Edwin spends $9 each month and Adam spends $7 each month. Function 1 shows a greater rate of change, because Adam spends $21 each month and Edwin spends $81 each month. Function 1 shows a greater rate of change, because Adam spends $7 each month and Edwin spends –$9 each month.
