Answer 1

B

Explanation:

I took the test :)

Answer 2

Short Answer: B

Explanation:

You want to solve for x in

• e^(4x - 1) = 3 Take the natural log of both sides
• ln(e^(4x - 1) ) = ln3 Bring the power down from the left side of the equation
• (4x - 1) ln(e) = ln(3) Note that ln(e) = 1
• (4x - 1)*1 = ln(3) Add 1 to both sides
• 4x - 1 + 1 = ln(3) + 1 Reduce
• 4x = ln(3) + 1 Divide by 4
• x = (ln(3) + 1)/4
