Situation: The answer is D because running up a hill first takes less time, which you can see in the graph. Then, walking up a hill takes more time and you are going upward, which is expressed in the graph. Next, you run down the hill, which takes less time than walking which is on the graph. Finally, you walk the remainder of the hill downwards, which takes more time and is shown in the graph. Hope this helps!
Answer:
Step-by-step explanation:
Slope-intercept form is 
where m is the slope
A. The slope is 8/5, and the -1/2 means that the point (0, -1/2) falls on the line, therefore the slope-intercept form is y+1/2=8/5(x-0) or y+1/2=8/5x
B. The slope is -5/8, and the 1/2 means that the point (0, 1/2) falls on the line, therefore the slope-intercept form is y-1/2=-5/8(x-0) or y+1/2=-5/8x
C. The slope is 5/8, and the 1/2 means that the point (0, 1/2) falls on the line, therefore the slope-intercept form is y-1/2=5/8(x-0) or y-1/2=5/8x
D. The slope is 8/5, and the 1/2 means that the point (0, 1/2) falls on the line, therefore the slope-intercept form is y-1/2=8/5(x-0) or y-1/2=8/5x

Answer:
243.01.
Step-by-step explanation:
The first term (a) = 324.
The common ratio (r) = -108/324 = -1/3.
So sum of 9 terms is:
S(9) = 324 * (1 - (-1/3)^9) / ( 1 - (-1/3)
= 324 ( 1 - (-0.00005076)) / 4/3
= 324 * 1.00005076 / 1.33333
= 243.012.
The unit consumption of gas can be obtained by dividing the total distance traveled in miles by the total gallons of gas consumed by the trip. This is shown below:
121.72 miles / 6.8 gallons = 17.9
Therefore, on a gallon of gas, Amir can travel 17.9 miles, which is letter B among the choices.
