Answer:
B
Step-by-step explanation:
The graph shows "days" in the x-axis and "cost" in the y-axis.
It says he left the car at airport for 5 days, so we need to find the cost he paid for 5 days.
We have to look at "5" in the x-axis. There is 4 and 6 given, so 5 would be between these two numbers. Now, from x = 5, we draw an imaginary straight line upwards towards the red line. That will approximately cross a little over $24 but a little lower than $30.
So, the cost would be between 24 and 30, but closer to 24.
From the answer choices, we can clearly see that this will be $26.00, answer choice B is right.
Answer:1/3x is the slope and -4 is the y-intercept
Step-by-step explanation
find -4 on the graph then go up 1 unit then over to the right 3 units
-2 sqrt (20) -sqrt (125)
-2 sqrt (4 * 5) - sqrt (5 * 25)
-2sqrt (4) * sqrt (5) - sqrt (5) sqt (25)
-2 * 2 * sqrt (5) - 5sqrt (5)
-4sqrt (5) -5sqrt (5)
-9sqrt (5)
The sequence is subtracting 5.5 each time:
19 - 5.5 = 13.5
30 - 5.5 = 24.5
24.5 - 5.5 = 19
so 24.5, or 24 1/2 is your answer
hope this helps
