The correct Answer is:
To solve the inequality \(2(x - 4) \leq \frac{1}{2}(5 - 3x)\) and find the smallest possible value of \(x^2\) where \(x\) is an integer, we can follow these steps: ### Step 1: Simplify the Inequality Start by distributing on the left side: \[ 2x - 8 \leq \frac{1}{2}(5 - 3x) \] ### Step 2: Eliminate the Fraction Multiply both sides of the inequality by 2 to eliminate the fraction: \[ 2(2x - 8) \leq 5 - 3x \] This simplifies to: \[ 4x - 16 \leq 5 - 3x \] ### Step 3: Rearrange the Inequality Now, let's move all terms involving \(x\) to one side and constant terms to the other side: \[ 4x + 3x \leq 5 + 16 \] This simplifies to: \[ 7x \leq 21 \] ### Step 4: Solve for \(x\) Now, divide both sides by 7: \[ x \leq 3 \] ### Step 5: Find Integer Values of \(x\) Since \(x\) is an integer, the possible integer values for \(x\) are \(3, 2, 1, 0, -1, -2, \ldots\) ### Step 6: Calculate \(x^2\) Now, we need to find the smallest possible value of \(x^2\): - If \(x = 3\), then \(x^2 = 9\) - If \(x = 2\), then \(x^2 = 4\) - If \(x = 1\), then \(x^2 = 1\) - If \(x = 0\), then \(x^2 = 0\) - If \(x = -1\), then \(x^2 = 1\) - If \(x = -2\), then \(x^2 = 4\) - If \(x = -3\), then \(x^2 = 9\) The smallest value of \(x^2\) is \(0\) when \(x = 0\). ### Conclusion The smallest possible value of \(x^2\) is: \[ \boxed{0} \]
