A car is driving down a road at a normal speed of 50 mph. It enters a hilly area of gradual incline and decline, where it must drive 50 miles uphill and then 50 miles downhill. If this 100-mile section of road takes 2.6 hours to
traverse instead of the expected 2 hours (the time it would take if the road was completely flat), determine the
speed that the hills add or subtract when going over.
A. 24 mph
B. 32 mph
C. 37 mph
D. 12.5 mph

Identify the initial amount a and the growth factor b in the exponential function. a(x)=680*4.3^x

What is the graph of the absolute value equation ? y=|x|-5

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions: y > 2x + 3y is less than negative 3 over 2 times x minus 4part a: describe the graph of the system, including shading and the types of lines graphed. provide a description of the solution area. (6 points)part b: is the point (â’4, 6) included in the solution area for the system? justify your answer mathematically. (4 points)
