Verified answer

Bab Nilai Mutlak
Matematika SMA Kelas X

|-3b + 2| > 8

-8 > -3b + 2 > 8
-8 - 2 > -3b + 2 - 2 > 8 - 2
-10 > -3b > 6
-10/-3 < -3b/-3 < 6/-3
10/3 < b < -2
b < -2 atau b > 10/3

HP = { b | b < -2 atau b > 10/3, b ∈ bilangan real }

Answer 2

Jawab :
|-3b+2|＞8
1. -3b + 2 > 8
-3b > 8 - 2
-3b > 6
b > -2
2. -3b + 2 < -8
-3b < -8 - 2 = -10
b < -10/-3
< 10/3
