7
(i) Solve the inequalities \(-2 \lt x + 2 \leqslant 5\)
(ii) On the number line, represent the solution to part (i).
(4)
| Scheme | Marks |
|---|---|
| (i) \(-2 - 2 \lt x\) and \(x \leqslant 5 - 2\) | M1 |
| \(-4 \lt x \leqslant 3\) | A1 |
(ii) | B2 ft |
| (4) |
Notes
M1: condone omission/addition of “equals” in inequalities
A1: cao accept \(x \gt -4\) and \(x \leqslant 3\) (both present)
B2 ft: ft for an inequality where range lies between − 5 and +5
If not B2ft then B1ft for correct values but wrong shading of end circles
