Zack used these steps to solve this equation:

Three-fourths y + 5 = negative three-fourths y minus 9. Step 1: StartFraction 6 Over 4 EndFraction y + 5 = negative 9. Step 2: StartFraction 6 Over 4 EndFraction y = negative 14. Step 3: (StartFraction 6 Over 4 EndFraction) StartFraction 6 Over 4 EndFraction y = negative 14 (StartFraction 6 Over 4 EndFraction). Step 4: y = negative 21.

When Zack checked his solution, it didn’t work. What was his mistake?

A tree casts a shadow 8 meters long. At the same time, a building 64 meters tall casts a shadow 16 meters long. To the nearest meter, what is the height of the tree?

Part C
Check your prediction in part B by graphing the relationship. Go to your Math Tools and open the Graph. Follow these steps to create your graph:

Click +DATA and type 0 in the x-column and 0 in the y-column to set the origin of your graph.
Then, enter values for length and width of each TV screen in the correct cells in the table.
Click PLOT to see the graph of your points.
Click +RELATIONSHIP and click LINEAR. Then, check the box for Best Fit. This passes a line through the points you created.
Should you make a mistake, click the X next to Data Points to start over.
You should now see a graph of the points in the relationship. When you you’re satisfied with the graph, take a screen capture of it and paste it in the answer field.
