Someone please convert this equation to slope intercept form: 2x - 3y = 6?

IgorLugansk [536]

Slope y-intercept form is: y=mx+b

All you have to do is rearrange the equation:

2x-3y=6
2x=6+3y
2x-6=3y

now divide both sides by 3
(2x/3)-(6/3)=(3y/3)

and it becomes
$y= \frac{2}{3}x-2$ x

Bonus: you can plug in any two values for x and y and you can see both equation gives the same answer!

Which of the following is the inverse of y=3x?

shtirl [24]

Answer-

<em>The inverse of $y=3^x$ is </em>

$\boxed{\boxed{y=\log_3 x}}$

<u>Solution-</u>

The given function is,

$y=3^x$

We can get the inverse by interchanging he variable x and y among themselves and then separating each variables.

So in the inverse would be,

$\Rightarrow x=3^y$

Taking log of both sides,

$\Rightarrow \log x=\log 3^y$

As,

$\log a^b=b\times \log a$

Applying the same,

$\Rightarrow \log x=y\times \log 3$

$\Rightarrow y=\dfrac{\log x}{\log 3}$

As,

$\log_b a=\dfrac{\log a}{\log b}$

Applying the same,

$\Rightarrow y=\log_3 x$

Therefore, the inverse of $y=3^x$ is $y=\log_3 x$ .
