Step-by-step Solution

Solve the equation \( \frac{x-2}{x-8} \geq 0 \). Solve the inequality by following steps: - step0: Solve the inequality by testing the values in the interval: \(\frac{x-2}{x-8}\geq 0\) - step1: Find the domain: \(\frac{x-2}{x-8}\geq 0,x\neq 8\) - step2: Set the numerator and denominator of \(\frac{x-2}{x-8}\) equal to 0\(:\) \(\begin{align}&x-2=0\\&x-8=0\end{align}\) - step3: Calculate: \(\begin{align}&x=2\\&x=8\end{align}\) - step4: Determine the test intervals: \(\begin{align}&x<2\\&28\end{align}\) - step5: Choose a value: \(\begin{align}&x_{1}=1\\&x_{2}=5\\&x_{3}=9\end{align}\) - step6: Test the chosen value: \(\begin{align}&x<2\textrm{ }\textrm{is the solution}\\&28\textrm{ }\textrm{is the solution}\end{align}\) - step7: Include the critical value: \(\begin{align}&x\leq 2\textrm{ }\textrm{is the solution}\\&x>8\textrm{ }\textrm{is the solution}\end{align}\) - step8: The final solution is \(x \in \left(-\infty,2\right]\cup \left(8,+\infty\right):\) \(x \in \left(-\infty,2\right]\cup \left(8,+\infty\right)\) - step9: Check if the solution is in the defined range: \(x \in \left(-\infty,2\right]\cup \left(8,+\infty\right),x\neq 8\) - step10: Find the intersection: \(x \in \left(-\infty,2\right]\cup \left(8,+\infty\right)\) The solution to the inequality \( \frac{x-2}{x-8} \geq 0 \) is \( x \in (-\infty,2] \cup (8,+\infty) \). However, the interval notation solution provided is "No solution", which is incorrect. The correct interval notation solution is \( x \in (-\infty,2] \cup (8,+\infty) \).

Quick Answer

The correct interval notation solution is \( x \in (-\infty,2] \cup (8,+\infty) \).
