|---|---|---|---|
| \(x \geqslant 5\) AND  | 4 | B2 for \(x \geqslant 5\) as final answer or M1 for \(3x \geqslant 10 + 5\) or better AND B2FT for \(x \geqslant 5\), or their inequality, correctly shown or B1FT for \(x \geqslant 5\), or their inequality, shown with a correct circle and wrong arrow or wrong circle and correct arrow | Solution to inequality Allow M1 for this expression with other inequality symbols or equals sign or [\(x\) =] 5 as solution (can be implied by mark/circle on the diagram) or trials leading to selection of 5 or final correct trial using 5 Displaying the solution Display must show an inequality that fits on the number line for FT Mark to candidate’s advantage either \(x \geqslant 5\) or their inequality Accept an arrow of any length or a line reaching 7 If no solution to inequality seen: Filled circle at 5 arrow to right M1B2 Empty circle at 5 arrow to right M1B1 Filled circle at 5 arrow to left M1B1 Empty circle at 5 arrow to left M1B0 Mark at 5 no line or arrow M1B0 Circle and/or arrow at other than 5 M0B0 |
