The speed of a delivery truck varies inversely with the time it takes to reach its destination. If the truck takes 4 hours to reach its destination traveling at a constant speed of 40 miles per hour, how long will it take to reach the same location when it travels at a constant speed of 80 miles per hour?

• A. 1 hour

• B. 1 1/2 hours

• C. 2 hours

• D. 2 1/2 hours

• The graph is reflected over the x-axis, vertically stretched by a scale factor of 3, horizontally shifted to the left 2 units, and shifted down 5 units.

• The graph is reflected over the y-axis, vertically stretched by a scale factor of 3, horizontally shifted to the left 2 units, and shifted down 5 units.

Two pipes are being used to fill a large tank at a construction site. One is red and the other is yellow. When both pipes are used together, they can fill the tank in 3 hours. The yellow pipe alone can fill the tank in 9 hours. If only the red pipe were used, which equation can be used to determine how long it would take to fill the tank?
