Answer:

x=\sqrt{338}

Step-by-step explanation:

a^2+b^2=c^2

x^2+x^2=26^2

2x^2=26^2

2x^2=676

/2           /2

x^2=338

\sqrt{x^2} =\sqrt{338}

x=\sqrt{338}

What is the Inverse Equation<br><br>f(x) =6x-1 ?? please I need help!​
Scrat [10]

Answer:

f^{-1}(x)=\frac{x+1}{6}

Step-by-step explanation:

So we have the function:

f(x)=6x-1

To find the inverse function, switch x and f(x), change f(x) to f⁻¹(x), and solve for f⁻¹(x). Therefore:

f(x)=6x-1

Switch:

x=6f^{-1}(x)-1

Add 1 to both sides:

x+1=6f^{-1}(x)

Divide both sides by 6:

f^{-1}(x)=\frac{x+1}{6}

And that's our answer :)

What is the quotient? URGENT!!
jeyben [28]

Answer:

The answer is A.

Step-by-step explanation:

You have to multiply by converting the second fraction into upside down :

\frac{4x + 1}{6x}  \div  \frac{x}{3x - 1}

=  \frac{4x + 1}{6x}  \times  \frac{3x  -  1}{x}

=  \frac{(4x + 1)(3x - 1)}{x(6x)}

=  \frac{12 {x}^{2}   -  4x + 3x - 1}{6 {x}^{2} }

=  \frac{12 {x}^{2} - x - 1 }{6 {x}^{2} }
