@organish_uzb 9 sinf algebradan 3 – bsb savollari ii - variant. 1. tenglamalar sistemasini yeching: (6 ball) � 𝑥𝑥 = 1 − 2𝑦𝑦 𝑥𝑥 + 𝑦𝑦2 = 4 2. funksiyaning aniqlanish sohasini toping: (8 ball) 𝑦𝑦 = �𝑥𝑥2 − 𝑥𝑥 − 30 3. tenglamalar sistemasini yeching. (10 ball) �𝑥𝑥 2 + 𝑦𝑦2 = 41 𝑥𝑥𝑥𝑥 = 20 4. tengsizliklar sistemasini yeching: (8 ball) �𝑥𝑥 2 − 5𝑥𝑥 + 6 ≤ 0 𝑥𝑥2 + 5𝑥𝑥 + 6 > 0 5. agar 𝑎𝑎 > 0 bo‘lsa, tengsizlikni isbotlang: (8 ball) 𝑎𝑎 + 49 2 + 𝑎𝑎 + 25 2 > 12√𝑎𝑎 javoblar @organish_uzb va https://www.test-uz.ru/ bsb: test-uz.ru/sor_uz.php chsb: test-uz.ru/soch_uz.php https://t.me/organish_uzb https://www.test-uz.ru/
