Foundation January 2019 Paper 1 Q9
9 \(h = 6q - 2u\)
(a) Work out the value of \(h\) when \(q = 3\) and \(u = -5\) (2)
\(B = 3m + 2p\)
(b) Work out the value of \(p\) when \(B = 2\) and \(m = 5\) (2)
| Scheme | Marks |
|---|---|
| Eg \(6 \times 3 - 2 \times -5\) or 18 and (−)10 | M1 |
| 28 | A1 |
| (2) |
Notes
M1: for correct substitution
| Scheme | Marks |
|---|---|
Eg \(2 - 15 = 2p\) or \(2p = -13\) oe or \(p = \dfrac{B - 3m}{2}\) | M1 |
| \(-\dfrac{13}{2}\) oe | A1 |
| (2) | |
| (4 marks) |
Notes
M1: for isolating \(2p\) in a correct equation
