What is the solution to this equation?
Tanzania [10]

Answer:

Option (D)

Step-by-step explanation:

Given equation is,

8e^{2x+1}=4

Taking natural log on both the sides of the equation,

\text{ln}(8e^{2x+1})=\text{ln}(4)

\text{ln}(2^3)+\text{ln}(e^{2x+1})=\text{ln}(2^2)

3ln(2) + (2x + 1)[ln(e)] = 2ln(2)

2n(2) - 3ln(2) = (2x + 1)

2x = -ln(2) - 1

2x=\text{ln}(\frac{1}{2})-1  [Since, -ln(2) = ln(1) - ln(2) = \text{ln}(\frac{1}{2})]

2x=\text{ln(0.5)}-1

x=\frac{\text{ln(0.5)-1}}{2}

Therefore, Option (D) will be the correct option.

Can they be written as a fraction and if so why
Kruka [31]

The first one can be written as a fraction because it is a repeating decimal.

The second one can be written as a fraction because it is a repeating decimal.

The third one can not be written as a fraction since it is nether terminating nor repeating.

The last one can be written as a fraction since it is a terminating decimal.

Is -4x+8y=24 and y=1\2x+7 perpendicular, parallel, or neither
Ugo [173]
-4x + 8y = 24 is equal to y=(1/2) + 3
so that would be parallel to y=(1/2)+7
to figure this out you just solve for y
