sam is observing the velocity of a car at different times. after three hours, the velocity of the car is 51 km/h. after five hours, the velocity of the car is 59 km/h.

part a: write an equation in two variables in the standard form that can be used to describe the velocity of the car at different times. show your work and define the variables used. (5 points)

part b: how can you graph the equation obtained in part a for the first six hours? (5 points)

question 3 (essay worth 10 points)
(05.02, 5.03 mc)

the graph shows the functions f(x), p(x), and g(x):

graph of function g of x is y is equal to 1 plus the quantity 1.5 raised to the power of x. the straight line f of x joins ordered pairs negative 5, 3 and negative 3, negative 1 and is extended on both sides. the straight line p of x joins the ordered pairs 0, 2 and negative 2, negative 3 and is extended on both sides.

part a: what is the solution to the pair of equations represented by p(x) and f(x)? (3 points)

part b: write any two solutions for f(x). (3 points)

part c: what is the solution to the equation p(x) = g(x)? justify your answer. (4 points)

question 4 (essay worth 10 points)
(05.06 hc)

the coordinate plane below represents a town. points a through f are farms in the town.

graph of coordinate plane. point a is at 1, 3. point b is at 3, 1. point c is at 3, negative 3. point d is at negative 4, 2. point e is at negative 1, 5. point f is at negative 3, negative 3.

part a: using the graph above, create a system of inequalities that only contains points d and e in the overlapping shaded regions. explain how the lines will be graphed and shaded on the coordinate grid above. (5 points)

part b: explain how to verify that the points d and e are solutions to the system of inequalities created in part a. (3 points)
