Answer:

<h2>Slope = 2</h2>

<u>Step-by-step explanation:</u>

co-ordinates = (2,2) and (-1,-4)

Slope = (y² - y¹) / (x² - x¹)

= (-4 - 2) / (-1 - 2)

= -6 / -3

= 6/3

= 2

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.

Write as an indicated operation: the difference of 17 and 1

koban [17]

Indicated operations is talking about what exactly the numerical equation is asking you to do, in this case I believe it would be written as 17 - 1
