- 1.A circle has equation x² + y² = 49. Work out the coordinates of the point(s) on the circle where the tangent is horizontal.
- 2.Which of these values of x is a solution of x² + 2x − 15 = 0?
- 3.Solve 4x − (2x − 6) = 18
- 4.Factorise fully 56x − 24
- 5.A number, n, is tripled and then 4.5 is added. The result is 22.5. Form an equation and solve it to find n.
- 6.Make x the subject of the formula y = (x − 4)/5.
- 7.The equation x³ = 6x + 20 can be solved using the iterative formula xₙ₊₁ = ∛(6xₙ + 20). Taking x₀ = 3, x₁ = 3.3620 correct to 4 decimal places. Using the full unrounded value of x₁, work out x₂ correct to 3 decimal places.
- 8.The nth term of a sequence is n² + 4n. Work out the term number, n, for which the term equals 45.
- 9.The simultaneous equations 2x + 3y = 12 and x − y = 1 are given. Work out the value of y.
- 10.A tram sets off from a stop. Its velocity-time graph rises in a straight line from 0 m/s to 12 m/s over the first 8 seconds, then stays constant at 12 m/s for a further 10 seconds. Work out the total distance the tram travels in these 18 seconds, using the area under the graph.
- 11.A number machine multiplies its input by 2 and then subtracts 5. Work out the output when the input is 6.
- 12.A gardener charges a fixed fee of £15 plus £8 for each hour worked. The total charge, £T, for a job lasting h hours is given by T = 15 + 8h. Work out the charge for a job lasting 4 hours, and identify what kind of statement T = 15 + 8h is.
- 13.The formula connecting speed, distance and time is v = s ÷ t. Work out v, in km/h, when s = 180 and t = 4.
- 14.Solve the inequality 5 − x ≤ 2.
- 15.A rectangle has area 24x + 18. Ffion factorises the area as 6(4x + 3). Work out the value of the area when x = 2, and decide whether 6 and (4x + 3) are correctly identified as factors of 24x + 18.
