1. Two cyclists, A and B, are going on a bike ride and are meeting at an orchard. They left
home at the same time. Functions A and B give their distance from the orchard, in miles,
after riding for x hours. The functions are defined by these equations:
A(x) = -21% + 48.5
B(x) = -16.8x + 42
For each question, explain or show your reasoning.
a. Which cyclist lives farther away from the orchard? How do you know?
b. Who will get to the orchard first? Explain your reasoning.

Let us imagine that the number of automobile accidents in a certain region are related to the regional number of registered automobiles in tens of thousands (b1), alcoholic beverage sales in $10,000 (b2), and decrease in the price of gasoline in cents (b3). furthermore, imagine that the regression formula has been calculated as: y = a + b1x1 + b2x2 + b3x3 where y = the number of automobile accidents, a = 7.5, b1 = 3.5, b2 = 4.5, and b3 = 2.5 calculate the expected number of automobile accidents for a football weekend if the region has 25,000 registered vehicles, $75,000 worth of beer is sold, and a gas war causes a 10 cent drop in a gallon of gas.
