Is the first fraction x/(x^2-4)?
anonymous
  • anonymous
no it is x/(x^2-9) @alekos
alekos
  • alekos
ok give me a minute to check your answer
anonymous
  • anonymous
ok:)
alekos
  • alekos
well done! that's correct
anonymous
  • anonymous
yay! Will you check another?
alekos
  • alekos
yep!

Dominique can ice cupcakes twice as fast as Houston. When they work together, Dominique and Houston can ice a large order of cupcakes in 5 hours. How many hours would it take Houston to ice them by himself?

a. 13/2 b. 1 c. 4 d. 15/2
alekos
  • alekos
ok give me a sec
anonymous
  • anonymous
kk
alekos
  • alekos
I dont get any of those choices?
anonymous
  • anonymous
i posted them up there hold on.
anonymous
  • anonymous
a. 13/2 b. 1 c. 4 d. 15/2
alekos
  • alekos
what i meant was that I dont get any of the choices you posted?
anonymous
  • anonymous
oh! I know, I don't understand either.
alekos
  • alekos
could be a typo?

Solve for x and determine if the solution is extraneous or not.
anonymous
  • anonymous
no, it's a dumb question. Can we do this one instead?
anonymous
  • anonymous
I got 3, non-extraneous
alekos
  • alekos
with the previous question I think it should be "how long would it take dominique on his own" Then you would get one of those choices
anonymous
  • anonymous
Ok. So for the previous question, i got 15/2 ?
alekos
  • alekos
Yep! thats it let me check the 3rd question
anonymous
  • anonymous
kk
alekos
  • alekos
it is 3 but it would be classed as extraneous because if you substitute this in the original fractions you get zero on the bottom line
anonymous
  • anonymous
Oh! Thanks:)

Last one because I have no idea how to solve this one but I got 1/3x
alekos
  • alekos
is that x^2 on the top and x^5 on the bottom?
anonymous
  • anonymous
x^2 on the top and x^3 on the bottom
alekos
  • alekos
It goes like this \[\frac{ 1/x ^{2} }{3/x ^{3} } = \frac{ 1 }{ x ^{2} }.\frac{ x ^{3} }{ 3 }\]
alekos
  • alekos
can you do the rest?
anonymous
  • anonymous
@alekos I got 1/3x
anonymous
  • anonymous
x^3/3x^2
alekos
  • alekos
No. I'll go a bit further.......... \[= \frac{ x ^{3} }{ 3x ^{2}}\]
alekos
  • alekos
now what do you get?
anonymous
  • anonymous
x/3x
alekos
  • alekos
here are the rules of exponents \[\frac{ x ^{a} }{ x ^{b} } = x ^{a-b}\]
anonymous
  • anonymous
So then I assume it would be 3x
alekos
  • alekos
No, the three stays on the bottom line
anonymous
  • anonymous
Then it would just be 3/x
anonymous
  • anonymous
sorry, x/3
alekos
  • alekos
yeah thats it
anonymous
  • anonymous
Yay! Thanks so much! <3
alekos
  • alekos
No problem. I enjoyed helping you out
alekos
  • alekos
you're a good student
