First, move 9x^2 to the right:

7y^2 = 42 - 9x^2

Then, divide 7 on both sides:

y^2 = 6 - 9/7 * x^2

Gabrielle's age is three times Mikhail's age. The sum of their ages is 56, what is Mikhail’s age?

4vir4ik [10]

Gabrielle's age is 3x (in which x is mikhail's age)
the sum is 56 so 3x+x=56

3x+x=56
4x=56
x=14

since x was mikhail's age, mikhail is 14 years old

Expand each expression

matrenka [14]

Answer:

Option B - $\ln(\frac{4y^5}{x^2})=\ln 4+5\ln y-2\ln x$

Step-by-step explanation:

Given : Expression $\ln(\frac{4y^5}{x^2})$

To find : Expand each expression ?

Solution :

Using logarithmic properties,

$\ln (\frac{A}{B})=\frac{\ln A}{\ln B}=\ln A-\ln B$

and $\ln (AB)=\ln A+\ln B$

Here, A=4y^5 and B=x^2

$\ln(\frac{4y^5}{x^2})=\frac{\ln 4y^5}{\ln x^2}$

$\ln(\frac{4y^5}{x^2})=\ln 4y^5-\ln x^2$

$\ln(\frac{4y^5}{x^2})=\ln 4+\ln y^5-\ln x^2$

Using logarithmic property, $\logx^a=a\log x$

$\ln(\frac{4y^5}{x^2})=\ln 4+5\ln y-2\ln x$

Therefore, option B is correct.
