Answer :
To determine the correct description for the term [tex]\(\frac{9}{x}\)[/tex] in the context of the problem involving Amy's hike, we should examine the given function for total time, [tex]\( T(x) = \frac{6}{x} + \frac{6}{x+1} \)[/tex], as well as understand what each of these terms represents:
1. [tex]\(\frac{6}{x}\)[/tex] represents the time it takes Amy to hike to the waterfall, where [tex]\(x\)[/tex] is Amy’s hiking speed in miles per hour.
2. [tex]\(\frac{6}{x+1}\)[/tex] represents the time it takes Amy to hike back to the ranger station, given that her speed on the way back is [tex]\(x + 1\)[/tex] miles per hour.
Now, let's analyze the given options in relation to [tex]\(\frac{9}{x}\)[/tex]:
A. Speed at which Amy hikes to the waterfall:
- The speed at which Amy hikes to the waterfall is [tex]\(x\)[/tex] miles per hour, not [tex]\(\frac{9}{x}\)[/tex].
B. Distance that Amy hikes to the waterfall:
- The distance Amy hikes to the waterfall is 6 miles, not [tex]\(\frac{9}{x}\)[/tex].
C. Time it takes Amy to hike back to the ranger station:
- The time it takes Amy to hike back is [tex]\(\frac{6}{x+1}\)[/tex], not [tex]\(\frac{9}{x}\)[/tex].
D. Time it takes Amy to hike to the waterfall:
- The time it takes Amy to hike to the waterfall is [tex]\(\frac{6}{x}\)[/tex], not [tex]\(\frac{9}{x}\)[/tex].
Given all the options, none of them describe the term [tex]\(\frac{9}{x}\)[/tex] accurately. Thus, based on the problem's context and the answer calculation, the correct interpretation is that none of the provided options directly describe [tex]\(\frac{9}{x}\)[/tex]. Therefore, the term [tex]\(\frac{9}{x}\)[/tex] does not correspond to any of the given choices correctly.
The correct conclusion here is that none of the given options (A, B, C, D) are a correct description of the term [tex]\(\frac{9}{x}\)[/tex].
1. [tex]\(\frac{6}{x}\)[/tex] represents the time it takes Amy to hike to the waterfall, where [tex]\(x\)[/tex] is Amy’s hiking speed in miles per hour.
2. [tex]\(\frac{6}{x+1}\)[/tex] represents the time it takes Amy to hike back to the ranger station, given that her speed on the way back is [tex]\(x + 1\)[/tex] miles per hour.
