Answer:

Option (a) is correct.

An equivalent expression to the given expression -(2n - 6) is -2(n - 3)

Step-by-step explanation:

Given : Expression - (2n - 6)

We have to find an equivalent expression to the given expression -(2n - 6)

Equivalent expression are expression that have same value but look different in writing.

Consider the given expression  -(2n - 6)

Solve the equation below for x. <br> 500 = 25e ^ (2x)
Zigmanuir [339]

Answer:

x = i π n + log(20)/2 for n element Z

Step-by-step explanation:

Solve for x:

500 = 25 e^(2 x)

500 = 25 e^(2 x) is equivalent to 25 e^(2 x) = 500:

25 e^(2 x) = 500

Divide both sides by 25:

e^(2 x) = 20

Take the natural logarithm of both sides:

2 x = 2 i π n + log(20) for n element Z

Divide both sides by 2:

Answer: x = i π n + log(20)/2 for n element Z
