The number of fish (f) in a fish tank increases when the number of algae blooms (a) decreases. Write the correct equation for this scenario, and solve for the number of fish when there are 4 algae blooms.
Algae Blooms Fish
10 10
25 4
f = 1a; f = 4
f = .1a; f = .4
f = 100 over a; f = 25
f = 100 over a; f = 400

@jim_thompson5910
jimthompson5910 (jim_thompson5910):
well the first answer choice is f = 1a
basically f = a
that is true for the first row but NOT true for the second row
so hopefully you see why choice A is eliminated?
OpenStudy (anonymous):
so its either c or d
jimthompson5910 (jim_thompson5910):
the function is definitely 100/a

now plug in a = 4 to find the value of f
OpenStudy (anonymous):
so its C
jimthompson5910 (jim_thompson5910):
yes
jimthompson5910 (jim_thompson5910):
since 100/a = 100/4 = 25
OpenStudy (anonymous):
thanks

can you open it?
jimthompson5910 (jim_thompson5910):
the table only shows g(x)
jimthompson5910 (jim_thompson5910):
I don't see f(x) anywhere
OpenStudy (anonymous):
it has f(x) on the graph but i dont understand this one

the graph doesn't show up. All I see is a table
OpenStudy (anonymous):
its a straight line up and down from-1 on the graph for f(x)
jimthompson5910 (jim_thompson5910):
can you post a screenshot of it?
jimthompson5910 (jim_thompson5910):
ok go ahead and post it when you're ready
OpenStudy (anonymous):
can you open that

can you attach it where it says "attach file" under the text box?
OpenStudy (anonymous):
i got it
jimthompson5910 (jim_thompson5910):
Thanks. That helps clear things up
jimthompson5910 (jim_thompson5910):
From what I see, f(x) is a complete vertical line that will NEVER cross the y axis. So it does not have any y-intercepts at all.
jimthompson5910 (jim_thompson5910):
Saying things like `g(x) has a larger y-intercept` or `they both have the same y-intercept` makes no sense

haha yes lol and it makes more since when i had to look at it for like 30 mins im tired now lol
jimthompson5910 (jim_thompson5910):
