Question

TOLONG DIJAWAB SECEPATNYA ! YANG BENAR GUE JADIIN YANG TERBAIK !
1. x + 4 > 9
2. x- 13 > 2
3. 2(p+1) 4. 1per2 (2p - 5) >garisbawah 1per3 (4p + 3)

Answer 1

1. x + 4 > 9
x +4 - 4 > 9 - 4
x > 5
HP = {6,7,8,...}
2.. x - 13 > 2
x - 13 + 13 > 2 + 13
x > 15
HP = {16,17,18,...}
3. 2(p + 1) = 2p + 2 (maaf ga tau)
4. ½ (2p - 5) ≥ ⅓ (4p + 3)
6 x ½ (2p - 5) ≥ 6 x ⅓ (4p + 3)
3 (2p - 5) ≥ 2 (4p + 3)
6p - 15 ≥ 8p + 3
6p - 6p -15 ≥ 8p - 6p + 3
-15 ≥ 2p + 3
-15 - 3 ≥ 2p + 3 - 3
-18 ≥ 2p
-18 : 2 ≥ 2p : 2
-9 ≥ p
HP = {-9,-10,-11,-12,....}
