Answer:

A x=5 y=-2

Step-by-step explanation:

y = x − 7 ; 3 x + 7 y = 1

y = x - 7

Substitute

x − 7 for y in 3 x + 7y = 1:

3x + 7y = 1

3x + 7(x-7) = 1

10x - 49 = 1

10x = 50

x = 5

Substitute:

y = 5 - 7

y = -2

Answer:

B. 1 + ln 2 - ln x

General Formulas and Concepts:

Algebra II

Natural logarithms ln and Euler's number e
Logarithmic Property [Multiplying]: $\displaystyle log(ab) = log(a) + log(b)$
Logarithmic Property [Dividing]: $\displaystyle log(\frac{a}{b}) = log(a) - log(b)$

Step-by-step explanation:

Step 1: Define

Identify

$\displaystyle ln(\frac{2e}{x})$

Step 2: Simplify

Expand [Logarithmic Property - Dividing]: $\displaystyle ln(\frac{2e}{x}) = ln(2e) - ln(x)$
Expand [Logarithmic Property - Multiplying]: $\displaystyle ln(\frac{2e}{x}) = ln(2) + ln(e) - ln(x)$
Simplify: $\displaystyle ln(\frac{2e}{x}) = ln(2) + 1 - ln(x)$
Rewrite: $\displaystyle ln(\frac{2e}{x}) = 1 + ln(2) - ln(x)$
