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

shtirl [24]

Answer-

The inverse of $y=3^x$ is

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

Solution-

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 $y=\log_3 x$ .

Evaluate if m=1 and n=2 what’s 15m/n+1-m^2+n

Jobisdone [24]

$\\ \sf\longmapsto \dfrac{15m}{n}+1-m^2+n$

$\\ \sf\longmapsto \dfrac{15(1)}{2}+1-(1)^2+2$

$\\ \sf\longmapsto \dfrac{15}{2}+3-1$

$\\ \sf\longmapsto \dfrac{15}{2}+2$

$\\ \sf\longmapsto \dfrac{15+4}{2}$

$\\ \sf\longmapsto \dfrac{19}{2}$

Given that (2*(x -3) ) / 8*( 2 y - 3) = 16*( x - y )

lyudmila [28]

Answer:

2 ^ (x - 3) ÷ 2 ^ 3(2y - 3)=2 ^ 4(x - y)

The two are common so we give it out then

x - 3 ÷ 6y - 9 =4x - 4y

x - 3 -4x - 4y = 6y -9

-3x -2y = -6

6=3x+2y
