Jawaban:
12. x >= 7
13. C
14. 9
15. D. -2 dan 4
16. C. 2
Penjelasan dengan langkah-langkah:
12. 3(2x - 1) >= 5x + 4
6x - 3 >= 5x + 4
6x - 5x >= 4 + 3
x >= 7
13. A = {x| x < 5, x € bilangan asli}
A = {1, 2,3,4}
B = {bilangan prima kurang dr 5}
B = {2,3}
B himpunan bagian dari A ---> opsi C
14. misal jml tdk mengikuti keduanya = x, maka
50 = 32 - 15 + 24 - 15 + 15 + x
50 = 17 + 24 + x
50 = 41 + x
x = 50 - 41
x = 9
15. f(-2) = 8 ---> -2p + q = 8
f(4) = -4 ---> 4p + q = -4
__________ -
-6p = 12
p = 12/-6
p = -2
-2p + q = 8
-2(-2) + q = 8
4 + q = 8
q = 8 - 4
q = 4
16. gradien = m
m = y2 - y1 / x2 - x1
m = 8 - 2 / 5 - 2
m = 6/3
m = 2
