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:[tex]2x-1\geq 0[/tex]
Rearrange terms to the left side of the equation:[tex]2x\geq 1[/tex]
Divide both sides of the inequality by the coefficient of the variable:
=> [tex]x\geq \frac{1}{2}[/tex]
The domain of the inequality is:[tex]x\geq \frac{1}{2}[/tex]
Convert logarithm to exponential form:[tex]2^{3}=2x-1[/tex]
Calculate the power:[tex]8=2x-1[/tex]
Rearrange terms to the left side of the equation:[tex]-2x= -8-1[/tex]
Calculate:[tex]-2x=-9[/tex]
Divide both sides of the equation by the coefficient of the variable:[tex]x=\frac{-9}{-2}[/tex]
=> [tex]x=\frac{9}{2}[/tex]
=>[tex]x=4.5\\[/tex]
Round the number: [tex]x=4.50[/tex]
Answer: [tex]x=4.50[/tex]
=> [tex]x=5[/tex]
