You didn't include the graphs. However, I can describe the graph for you, so you can select the correct graph.
First, the car slows. So look for a line segment that is pointing down diagonally. Then, it maintains the speed. Look for a line that is horizontal. Finally, it slows down again to a stop. Look for a line segment that slants downward and touches the x axis.
Answer:
Barney 145 3 Days 310 Miles
Mary 250 5 Days 600 Miles
A) 3 D + 310 M = 145
B) 5 D + 600 M = 250
Multiplying A) by -5/3
A) -5 D - 516.6666M = -241.66666666
B) 5D + 600M = 250
Adding A) and B)
83.3333 M = 8.3333333333
M = .10 per mile
3 D = 114
Daily Rate = 38 dollars per day

Answer:
The length of the rectangle is 7x + 27
Step-by-step explanation:
Given;
area of the rectangle, A = 21x + 81 units²
width of the rectangle, w = 3 units
let the length of the rectangle, = L
Area of the rectangle = length x width
A = L x w
21x + 81 = 3L
L = ¹/₃(21x + 81)
L = 7x + 27
Therefore, the length of the rectangle is 7x + 27
