MATEMATIKAMAVZU: MASALALAR YECHISH 6- sinf Manfiy son Musbat son O‘ziga teng Manfiy songa qarama-qarshi son qanday son bo‘ladi? To‘g‘ri!
0 TAKRORLASH Musbat son Manfiy son 0 To‘g‘ri!
Teskari son TAKRORLASH Musbat songa qarama-qarshi son qanday son bo‘ladi? Manfiy son Musbat son O‘ziga teng Manfiy sonning moduli qanday son? To‘g‘ri!
0 TAKRORLASH 0 Manfiy son Noldan kichik son To‘g‘ri!
Musbat son TAKRORLASH Musbat sonning moduli qanday son? Manfiy son 0 0 dan katta 0 sonning moduli qanday son? To‘g‘ri!
Musbat son TAKRORLASH TOPISHMOQ 1. Shunday musbat son o‘ylandiki, uning moduli 3 ga teng. O‘ylangan sonni toping. 2. Shunday manfiy son o‘ylandiki, uning moduli 7 ga teng. Qanday son o‘langan. 3. Farrux shunday son o‘yladiki, uning moduli 0 ga teng. Farrux o‘ylangan sonni toping. Javob: 3 Javob: -7 Javob: 0 SONNING MODULI │a - b│ son koordinata to‘g‘ri chizig‘ida A (a) nuqtadan B(b) nuqtagacha bo‘lgan masofani bildiradi. MISOL │2 – (–3)│ = │ 2 + 3 │= │5 │= 5 bu 2 va -3 nuqtalar orasidagi masofadir
Demak, x va 2 nuqtalar orasidagi masofa 2 ga teng 3 3 1. │x - 2│ = 3 tenglamani yeching. x = -1 va x = 5
2. │x│ = 4 tenglamani yeching. Yechish: │4│ = 4
│- 4│ = 4 x = 4
x = - 4 3. │x - 3│ = 0 tenglamani yeching. Yechish: x = 3
x - 3 = 0 728- masala Koordinata to‘g‘ri chizig‘idan foydalanib, qo‘sh tengsizlikning butun yechimlarini toping: 1) 12,8< x < 19,1 3) -9< x < -2 2) -3,2 < x < 4,7
x ning tenglik o‘rinli bo‘ladigan qiymatini toping: 1) – x = - 3 3) – x = - ( +7) 2) – x = 5 x = 3
x = -5 x = 7
4) – ( - x) = 2 x = 2
739- masala Tenglamani yeching: 1) │x - 8 │ = 0 3) │x│- 4 = 0 2) │– x │ = 9 4) │-x│ = -16 740- masala 1) – x = 3 3) – 18 = - x 2) – x = - 3 4) – 18 = x Tenglamani yeching: MUSTAQIL BAJARISH UCHUN TOPSHIRIQLAR:MUSTAQIL BAJARISH UCHUN TOPSHIRIQLAR:Darslikning 138- betidagi748-, 753-, 754-, 755- masalalarniyeching.Yüklə 243,53 Kb.
