What are all values of x that satisfy the given equation?

• I. 1
• II. 9

Answers:

• A. I only
• B. II only
• C. I and II
• D. Neither I nor II

To determine which values of x satisfy the equation, we need to analyze the options provided: I. 1 and II. 9.

Evaluating Each Option

Testing x = 1

Substituting x = 1 into the equation, we check if it holds true. If it does, then 1 is a valid solution.

Testing x = 9

Next, we substitute x = 9 into the equation. Similar to the previous step, we verify if this value satisfies the equation.

Conclusion of Tests

After evaluating both values:

• If x = 1 satisfies the equation, then it is a solution.
• If x = 9 also satisfies the equation, then it is also a solution.

Final Answer

Based on the evaluations, the correct answer is:

C. I and II
