Answer:

x=8°

y=29°

Step-by-step explanation:

vertically opposite angles are equal

so 5x+9°=y+20°

therefore 5x-y=11°

Alternate angles are equal

so 4x+17°=y+20°

therefore 4x-y=3°

equation 1....... 5x-y=11°

equation 2......4x-y=3°

using elimination method x=8°

y=29°

What is the first step in solving ln(x − 1) = ln6 − lnx for x?

Stels [109]

Answer:

Option C - Simplify the right side using the "difference of two logs is the log of the quotient" property.

Step-by-step explanation:

Given : Expression $\ln (x-1)=\ln 6-\ln x$

To find : What is the first step in solving the expression ?

Solution :

Expression $\ln (x-1)=\ln 6-\ln x$

Step 1 - Simplify the right side using the "difference of two logs is the log of the quotient" property.

i.e. $\ln a-\ln b=\ln(\frac{a}{b})$

Apply the first step we get,

$\ln (x-1)=\ln(\frac{6}{x})$

Therefore, Option C is correct.
