• Sep 29, 2025 chapter 3 systems of equations and inequalities ary. Draw the boundary line: Use a solid line for ≤ or ≥ (including equality). Use a dashed line for < or > (strict inequalities). Shade the region that satisfies the inequality: Test a point not on the boundary (e.g., (0,0)) to determine which side to sha By Joy Turcotte
• Nov 12, 2025 algebra 2 linear inequalities answer key ng all points to the left. Problem 2: Solve: -2x + 4 ≥ 8 Subtract 4: -2x ≥ 4 Divide both sides by -2 (remember to reverse the sign): x ≤ -2 Answer key confirms the solution x ≤ -2, with a solid line on x=-2, shading to the left. Problem 3: Graph the inequality y > 2x By Keon Rosenbaum
