Inverse of y=14x2 show derivations

Rudik [331]

<h2>Answer:</h2>

$f^{-1} (x)=\sqrt{\frac{x}{14}}$ .

<h2>Step-by-step explanation:</h2>

<h3>1. Write the expression.</h3>

$y=14x^2$

<h3>2. Substitute y for x, and x for y.</h3>

$x=14y^{2}$

<h3>3. Solve for y.</h3>

$14y^{2}=x\\ \\y^{2} =\frac{x}{14} \\ \\y=\sqrt{\frac{x}{14}}$

<h3>4. Express your result.</h3>

$f^{-1} (x)=\sqrt{\frac{x}{14}}$ .

A computer scans every 2.75 days and another scans every 3.5 days

Brut [27]

Answer:

Alright, so we have to find the LCM of 2.75 and 3.5.

A good start would be to multiply them together to get 9.625, but we want a whole day!

This would be every 77 days :)

81+7x=81 what does x equal?

cupoosta [38]

So to start off here is the question being asked:
81+7x=81
The first thing we are going to do is simplify both sides of the equation:
7x+81=81
Second thing to do is subtract 81 from both sides so:
7x+81−81=81−81
The final thing to do is divide both sides by 7:
7x/7=0/7
The final answer is:
x=0

I hope this helps! :)
