After crossing a bridge, Greg drives at a constant speed. The graph below shows the distance (in miles) versus the time since he crossed the bridge (in hours). Use the graph to answer the questions.

Solve the equation 3x2 + 19x + 9 = 0 to the nearest tenth.

Brook states that the distance on the line is 4 units. caleb states that the whole line does not have a distance because it continues on forever. vivian states that the line is 6 units long. which distance did brook measure? which distance did vivian measure?

One of the inventors of integrated circuits observed that the number of transistors that fit on an integrated circuit will double every 24 months. what type of relationship most appropriately models this situation?
