5. Jawab: C

6. Jawab: C

7. Jawab: A

f(x) = x2 – 2x – 8 ; Titik potong dengan sumbu X y = 0

x2 – 2x – 8 = 0 (x – 4) (x +2) = 0 (4,0) dan (-2,0)

8. Jawab: C y = -2x2 + 12x – 13

Titik balik (3,5)

9. Jawab: C

Puncak (1,5) ; Titik potong dengan sumbu y (0,3)

10. Jawab: B

“Saya tidak belajar Matematika”



11. Jawab: A a = 1 ; b = 2 ; c = 3 ; d = 1

12. Jawab: C x2 – 3x – 10 = 0 (x – 5) (x + 2) = 0 x = 5 dan x = -2

13. Jawab: C 2x2 – x – 3 = 0

x2 – ( + )x + ( . ) = x2 – (2)x + (-24) x2 – 2x – 24 = 0

14. Jawab: C

x2 + 2x + 3 = 0

15. Jawab: D

+ - + -2 < x < 3

-2 3

16. Jawab: D 4x + 3y = 13 4x - 4y = -8 -

7y = 21 7y = 3

17. Jawab: D

2x + 3y = 12.000 ; 4x + y = 14.000

18. Jawab: D 2A + B 800 2A + B 500 -

2A = 300

x – 3 = - 2 x = 3 – 2 = 1

x1 + y1 = 1 + 3 = 4

300 + B = 500 B = 500 – 300 = 200



19. Jawab: C (0,5) & (4,0) 5x + 4y = 20 5x + 4y 20

(0,4) & (8,0) 4x + 8y = 32 x + 2y 8

5x + 4y 20 ; x + 2y 8 ; x 4

20. Jawab: D A + 2B 18 A + 2B 26 -

2B = 8

(10, 8) 2000 (10) + 3000 (8) = 20.000 + 24.000 = 44.000

21. Jawab: E

2a – b = 3 ; 2b – a = 0 a = 2b

2 (2b) – b = 3 4b – b = 3 3b = 3 b = 1

2a – 1 = 3 2a = 4 a = 2

a + b = 2 + 1

22. Jawab: E

23. Jawab: -

24. Jawab: C Aritmatika ; a = 5 ; U3 = 9

U3 = a + 2b = 9 9 = 5 + 2b 2b = 4 b = 2

S20 = ½ n [2a + (n – 1)b] = ½ (20) [2.5 + (20-1)2] = 480

25. Jawab: B Geometri ; a = 16 ; U4 = 2

U4 = a . r(n-1) 2 = 16 . r3 r3 = ⅛ r = ½

26. Jawab: C

2x2 – x – 6 (2x + 3)(x – 2)

x2 + x – 6 (x + 3)(x – 2)

A + 8 = 18 A = 18 – 8 = 10



27. Jawab: E

a = 1 ; b = 2 ; c = 1 ; d = 1 ; e = -3 ; f = 4

28. Jawab: D f(x) = ⅓x3 – 3x2 + 5 f’(x) = x2 – 6x

29. Jawab: C y = x2 – x + 2 y = m = 2x – 1 ; (1,2) m = 2(1) – 1 = 1

y – 2 = 1 (x – 1) y = x + 1

30. Jawab: D

31. Jawab: B Kpersegi panjang = 2 (p + l) 200 = 2 (p + l) p + l = 100 p = 100 - l

L = p x l = (100 - l) l = - l2 + 100l

l2 - 100l + 2500 = 0 (l – 50)2 = 0 l = 50 p = 100 – 50 = 50

32. Jawab: B 0, 1, 2, 3, 4, 5, 6, 7

7 (8 – 1) (8 – 2) = 7 x 7 x 6 = 294

33. Jawab: D n = 6 ; r = 2

34. Jawab: B n = 8 ; r = 3

35. Jawab: E Jumlah mata dadu 8 = (2,6), (3,5), (4,4), (5,3), (6,2) ; n(8) = 5 ; n(sampel) = 36



36. Jawab: C (A,A), (A,G), (G,A), (G,G) ; n = 2

37. Jawab: A 20 tahun = 17% ; n = 100

38. Jawab: C
