∑ Hey, eduardolozanosalgado ⊃

Answer:

x=24 , y=68

Step-by-step explanation:

Given:

$\mathrm{\begin{bmatrix}x+y=92\\ y=3x-4\end{bmatrix}}$

Solution:

Substitute: $\mathrm{y = 3x-4}$

$\begin{bmatrix}x+3x-4=92\end{bmatrix}$

Isolate x for 4x - 4= 92 : x = 24

Substitute : x = 24

$y=3\cdot \:24-4$

$y=64$

Hence, the solutions are : $x=24,\:y=68$

Y=log base(rootx) x find dy/dx

Fudgin [204]

Given:

$y=\log_{\sqrt{x}}x$

To find:

The value of $\dfrac{dy}{dx}$ .

Solution:

We have,

$y=\log_{\sqrt{x}}x$

It can be written as

$y=\log_{\sqrt{x}}(\sqrt{x})^2$

Using property of log, we get

$y=2$ $[\because \log_aa^x=x]$

Now, differentiate both sides with respect to x.

$\dfrac{dy}{dx}=\dfrac{d}{dx}(2)$

$\dfrac{dy}{dx}=0$ $[\because \dfrac{d}{dx}(Constant)=0]$

Therefore, the value of $\dfrac{dy}{dx}$ is 0.
