## anonymous one year ago Find the x intercept for: y=2-√x / 5x

1. Astrophysics

Set y = 0 and solve for x

2. Astrophysics

$y=\frac{ 2-\sqrt{x} }{ 5x }$ is it this

3. anonymous

Yes

4. Astrophysics

Ok let y = 0 and solve for x as I suggested

5. Astrophysics

$\frac{ 2-\sqrt{x} }{ 5x }=0$

6. anonymous

So 5x=2-√x

7. Astrophysics

Not quite, remember you have to multiply both sides by 5x, so we have 5x * 0 = 0 right? So $2-\sqrt{x}=0$

8. anonymous

Thank you! I just couldn't see what i was missing but its multiplication of both sides not subtraction -.-

9. anonymous

Very appreciated!

10. Astrophysics

Np, so lets just finish it off, what did you get

11. anonymous

-√x = 2 square both sides -x = 4 x+-4

12. anonymous

x = -4

13. Astrophysics

Well it would be better if you just move $-\sqrt{x}$ to the right side so we have $2-\sqrt{x}=0 \implies 2 = \sqrt{x} \implies x = 2^2 = 4$

Maybe i'm just not looking at everything correct today =/ I'm sorry!

15. Astrophysics

It's cool
