Step 1: Rewrite the inequality: \[ 2x + 3y>6 \quad \Rightarrow \quad y>-\frac{2}{3}x + 2. \] Step 2: The inequality represents the region above the line \( 2x + 3y = 6 \), excluding the points on the line.
Since \( 2(0) + 3(0) = 0 \not > 6 \), the origin is not part of the solution.
If vector \( \mathbf{a} = 3 \hat{i} + 2 \hat{j} - \hat{k} \) \text{ and } \( \mathbf{b} = \hat{i} - \hat{j} + \hat{k} \), then which of the following is correct?
