Which of the following logarithm expressions are equivalent to sqrt xy in (e/x)

Answer

D)

Step by step explanation

We have to use the log rules.

The given expression can be written

       [Use the quotient rule]

                [Use product rule : ln(x) + ln(y) = ln(xy)

                                                            and ln(e) = 1]

The answer is

Thank you.

step-by-step explanation:

it's 15

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
