What is the value of log 27^9?

KengaRu [80]

Answer: The answer is $\dfrac{2}{3}.$

Step-by-step explanation: We are given to find the value of $\log_{27}9.$

Here, we will be using the following properties of logarithm.

$(i)~\log a^b=b\log a,\\\\(ii)~\log_ba=\dfrac{\log a}{\log b}.$

So, we will be solving the given problem using these two as follows.

$\log_{27}9=\dfrac{\log9}{\log27}=\dfrac{\log 3^2}{\log 3^3}=\dfrac{2\log 3}{3\log 3}=\dfrac{2}{3}.$

Thus, the required value is $\dfrac{2}{3}.$

What is the equation of the line ?

Akimi4 [234]

Answer: OPTION A

Step-by-step explanation:

The equation of the line, by definition, has the following form:

y=mx+b

Where m is the slope and b is the y-intercept.

Calculate the slope as following:

$m=\frac{5-(-3)}{4-(-2)}=\frac{4}{3}$

Now, you must solve for the y-intercept, as you can see below:

$5=\frac{4}{3}(4)+b\\ b=-\frac{1}{3}$

Then, the equation of the line is:

$y=\frac{4}{3}x-\frac{1}{3}$

-4 + 3y = -43<br> what does y equal?

NeTakaya

Answer:

-13

Step-by-step explanation:

We remove the -4 by adding 4 to each side:

3y = -43 + 4

Now we simplify to give:

3y = -39

So now we divide both sides by 3 to give our answer of:

y = -39/3
y = -13
We can substitute this into the original equation to check our answer:

-4 + 3(-13) = -43

-4 + -39 = -43
