1. The problem involves evaluating or simplifying the given functions: - $f(x) = 2x - 5$ - $5x - 2$ - $\frac{x + 5}{2}$ - $\frac{x - 5}{2}$ - $2x + 5$ 2. Since no specific operation (like solving for $x$ or evaluating at a point) is requested, we can interpret "give me the answer" as simplifying or comparing these expressions. 3. Let's analyze each expression: - $f(x) = 2x - 5$ is a linear function. - $5x - 2$ is another linear function. - $\frac{x + 5}{2}$ is a linear function rewritten as $0.5x + 2.5$. - $\frac{x - 5}{2}$ is a linear function rewritten as $0.5x - 2.5$. - $2x + 5$ is a linear function. 4. If the question is to find which expressions are equal or to simplify, none of these expressions are equal to each other for all $x$. 5. If you want to evaluate any of these functions at a specific $x$, please provide the value. Final answer: The expressions are distinct linear functions and cannot be simplified further without additional context.
