For the question mark, we can insert a variable considering it is an unknown number.

\frac{3^6}{3^x}  =  3^4 \\ \\ 3^{6-x} = 3^4 \ / \ use \ qotient \ rule \\ \\ 6 - x = 4 \ / \ cancel \ out \ 3 \\ \\ -x = 4 - 6 \ / \ subtract \ 6 \ from \ each \ side \\ \\ -x = -2 \ / \ simplify \\ \\ x = 2 \ / \ multiply \ each \ side \ by \ -1 \\ \\ Answer: \fbox {x = 2}

Answer:

y=-6/5x - 1

Step-by-step explanation:

Slope intercept form is y=mx+b so first lets get it into correct order by subtracting the 6x to the other side.

6x-6x+5y=-5-6x

This gives you

5y=-6x-5

Now you need to isolate the y since the 5 is being multiplied by the variable "y" we need to divide to to separate. Divide all terms by 5.

5y/5=-6/5x+(-5)/5

This gives you your final answer:

y=-6/5x - 1

Answer:

     =4sqrt(10)

Step-by-step explanation:

The geometric mean of two numbers is sqrt(a*b) where a and b are the two numbers

geometric mean = sqrt(8*20)

                            =sqrt(160)

                             = sqrt(16*10)

We know that sqrt(ab) = sqrt(a) sqrt(b)

                            =sqrt(16) sqrt(10)

                             =4sqrt(10)
