(Total for Question 20 is 3 marks)

Question 1 (4 marks)

Gradient from origin to point (1, 1) is 1 ÷ 1 = 1.
Gradient of L is -1 ÷ 1 = -1.
Equation of L is of the form y = -1x + c.
Substituting in (1, 1) gives c = 2.
Equation of L is y = -1x + 2.
When y = 0, x = 2 so P is the point (2, 0).

Question 2 (4 marks)

Gradient from origin to point (8, 4) is 4 ÷ 8 = 0.
Gradient of L is -1 ÷ 0 = -2.
Equation of L is of the form y = -2x + c.
Substituting in (8, 4) gives c = 20.
Equation of L is y = -2x + 20.
When y = 0, x = 10 so P is the point (10, 0).

Question 3 (4 marks)

f(0) = -10, so the graph crosses the f(x) axis at (0,
-10).
Completing the square gives f(x) = (x +1)² -11 so
the coordinates of the turning point (minimum) are
(-1, -11).
The graph crosses the x axis when (x +1)² -11 = 0.
Solving gives x = -1 ±√11.
The graph crosses the x axis at (-1-√11, 0) and
(-1+√11, 0).

Question 4 (4 marks)

Rearranging gives x² -10x +24 > 0.
Factorise to get (x-6)(x-4) > 0.
Therefore x < 4 and x > 6.

Question 5 (6 marks)

Question 11 (3 marks)

Expanding and simplyfying the first two pairs of
brackets gives:
(16x²-8x-63)(x-10).
Now expand and simplify to get:
16x³-168x²+17x+630.

Question 12 (2 marks)

20q² - 80r² = 5(4q² - 16r²)
Factorising using difference of two squares gives:
5(2q + 4r)(2q - 4r).

Question 13 (4 marks)

Gradient from origin to point (8, 8) is 8 ÷ 8 = 1.
Gradient of L is -1 ÷ 1 = -1.
Equation of L is of the form y = -1x + c.
Substituting in (8, 8) gives c = 16.
Equation of L is y = -1x + 16.
When y = 0, x = 16 so P is the point (16, 0).

Question 14 (4 marks)

Gradient of AB is 10 ÷ 2 = 5.
Gradient of line perpendicular to AB is -1/ 5.
Equation of perpendicular is of the form y = -1/ 5 x +
c
At the point C, (-3) = -1/ 5 (-5) + c.
c = -4.
x + 5y = -20.

Question 15 (4 marks)

Rearranging gives x² -3x -4 ≥ 0.
Factorise to get (x-4)(x+1) ≥ 0.
Therefore x ≤ -1 and x ≥ 4.

Mark Scheme - Total Marks: 75

Equation of L is of the form y = -0 + c.
Substituting in (1, 5) gives c = 5.
Equation of L is y = -0 + 5.
When y = 0, x = 26 so P is the point (26, 0).

Question 10 (6 marks)

a) 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ...
1st term is 1e + 0f
2nd term is 0e + 1f
3nd term is 1e + 1f
4rd term is 1e + 2f
5th term is 2e + 3f
6th term is 3e + 5f
c) We have a pair a simultaneous equations:
1e + 1f = 21
3e + 5f = 89
Solving these gives e = 8 and f = 13

Question 20 (3 marks)

Expanding and simplyfying the first two pairs of
brackets gives:
(8x²+10x-7)(2x+3).
Now expand and simplify to get:
16x³+44x²+16x-21.
