Question

Find the x intercept for:
y=2-√x / 5x

Answer 1

Set y = 0 and solve for x

Answer 2

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

Answer 3

Yes

Answer 4

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

Answer 5

\[\frac{ 2-\sqrt{x} }{ 5x }=0\]

Answer 6

So 5x=2-√x

Answer 7

Not quite, remember you have to multiply both sides by 5x, so we have 5x * 0 = 0 right?

So \[2-\sqrt{x}=0\]

Answer 8

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

Answer 9

Very appreciated!

Answer 10

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

Answer 11

-√x = 2
square both sides
-x = 4
x+-4

Answer 12

x = -4

Answer 13

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

Answer 14

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

Answer 15

It's cool
