Question

Tolong dijawab ya tentang PtLSV
A. 2x-5>9
b. 2+5≤7
c. Ykuadrat-16≤36
d. 7/p+3≥20
e. 1/q-4q≤23
f. a+2b>-17

Answer 1

A. 2x-5>9
2x > 9+5
2x > 14 → x > 7
b. ???
c. y² - 16 ≤ 36
y² ≤ 36+16
y² ≤ 52
y ≤ √52 → y ≤ √(4×13)→ y ≤ 2√13
d. → 7/p ≥ 20 - 3
→ 7/p ≥ 17
→ p ≥ 17×7
→ p ≥ 119
e. 1/q - 4q ≤ 23
1 - 4q² ≤ 23q
1- 4q² - 23q ≤ 0
-4q² - 23q +1 ≤ 0
4q² + 23q -1 ≥ 0
f. ???
semoga dapat membantu
