Step-by-step solution
4 stepsHuu hapa ni ufumbuzi wa swali la 5:
Tunahitaji kutatua usawa .
Usawa huu unaweza kugawanywa katika sehemu mbili:
Tatua usawa wa kwanza.
Toa kutoka pande zote mbili:
Toa 2 kutoka pande zote mbili:
Hii inamaanisha .
Tatua usawa wa pili.
Jumlisha kwa pande zote mbili:
Toa 2 kutoka pande zote mbili:
Gawanya kwa 4:
Unganisha suluhisho.
Tunayo na .
Kuunganisha hizi kunatupa masafa ya :Wakilisha suluhisho kwenye mstari wa namba.
Kwenye mstari wa namba:
- Weka duara lililojazwa (au nukta iliyotiwa kivuli) kwenye -6, kuashiria kuwa -6 imejumuishwa.
- Weka duara wazi (au nukta isiyo na kivuli) kwenye 2, kuashiria kuwa 2 haijajumuishwa.
- Chora mstari unaounganisha duara hizi mbili.
