Homework Statement


5/8x + 1/16x= 9/16 + x


Homework Equations





The Attempt at a Solution


10x+ x = 9+16
11x=9+16x
-5x=9
x= - 9/5
x =- 1.8

Is this correct. I am trying to make sure I am in the right direction


Also is f(x) = 2x^2-2x
f(0) = I got )
f(-1) I got 4
f(2) Igot 4

Is this correct also..

I need to make sure that this one is correct also

What is the domain of g(x) = 3/5-3x
I got that x is not equal to 5/3.

I hope I got all these right...

I think you have a typo for f(0), what did you get? I agree with your answer for f(-1) and f(2). If part 1 has the x upstairs in the fractions like,
(5*x)/8 + (1*x)/16 = 9/16 + x
then I agree with your answer. But not if it is downstairs like,
5/(8*x) +1/(16*x) = 9/16 +x

I'm not sure I agree with your domain of g(x). What is your reasoning for 5/3?

Because I can not see g(x) = 3/5-3x answers being either a.not equal to 3, b. equal to 0. or c x greater than or equal to 5/3..My head is spinning numbers maybe I am wrong

and for f(0) = 2x^2 -2x when you mutiply be zero the answer is 0..right?

The problem with the domain question is that we were not sure if you meant
[tex]g(x) = \frac{3}{5 - 3x}[/tex]
or
[tex]g(x) = \frac{3}{5} - 3x.[/tex]

It looks like you meant the former. (That is why it's helpful to learn LaTex. :wink:) Anyway, you're right -- the domain is
[tex]x \neq \frac{5}{3}.[/tex]
