What is the solution to the equation below? Round your answer to two
noname [10]

Answer:

D. x=5

The answer is x=4.50 then it is rounded off to 5. So, the answer is 5.

Step-by-step explanation:

Find the domain of the inequality:2x-1\geq 0

Rearrange terms to the left side of the equation:2x\geq 1

Divide both sides of the inequality by the coefficient of the variable:

=> x\geq \frac{1}{2}

The domain of the inequality is:x\geq \frac{1}{2}

Convert logarithm to exponential form:2^{3}=2x-1

Calculate the power:8=2x-1

Rearrange terms to the left side of the equation:-2x= -8-1

Calculate:-2x=-9

Divide both sides of the equation by the coefficient of the variable:x=\frac{-9}{-2}

=> x=\frac{9}{2}

=>x=4.5\\

Round the number: x=4.50

Answer: x=4.50

=> x=5
