1MA0 Higher June 2012 Paper 2 Q10
10 \(m\) is an integer such that \(-2 \lt m \leqslant 3\)
(a) Write down all the possible values of \(m\). (2)
(b) Solve \(7x - 9 \lt 3x + 4\) (2)
| Answer | Mark | Notes |
|---|---|---|
| \(-1\), 0, 1, 2, 3 | 2 | B2 for all 5 correct values; ignore repeats, any order. (–1 for each omission or additional value) |
| Working | Answer | Mark | Notes |
|---|---|---|---|
| \(7x - 3x \lt 4 + 9\) \(4x \lt 13\) | \(x \lt 3.25\) | 2 | M1 for a clear intention to use a correct operation to collect \(x\) terms or non-\(x\) terms in an (in)equality A1 for \(x \lt 3.25\) oe (SC: B1 for 3.25 oe seen if M0 scored) |
