Answer 1

11. 4 x 4.000 + 6 x 1.800 
16.000 + 10.800
= 26.800,-
= 50.000 - 26.800
= 23.200,- (B)

12. himpunan bilangan prima kurang dari 27
{2, 3, 5, 7, 11, 13, 17, 19, 23} = 9 bilangan
2⁹ = 512 (D)

13. (45 + 30 + 10) - 60
= 85 - 60
= 25 orang (B)

14.
f(2) = (2)a + b = 9
f(4) = (4)a + b = 1

4a + b = 1
2a + b = 9
------------- -
2a = -8
a = -4

4(-4) + b = 1
-16 + b = 1
b = 1 -(-16)
b = 1 + 16
b = 17

ax + b
f(1) = -4 x 1 + 17
f(1) = -4 + 17
f(1) = 13(B)
