Systems ntawm linear equations ua tau nkaus xwb muaj 0, 1, lossis tus lej tsis kawg kev daws teeb meem . Ob tug no kab tsis tuaj yeem hla ob zaug. Cov lus teb raug yog qhov system muaj ib daws.
Ib yam li ntawd, ib tug yuav nug, pes tsawg txoj kev daws teeb meem ib kab sib txuas muaj?
Yog li ntawd, lub coordinates ntawm lub point yog lub daws rau ob lub variables siv nyob rau hauv equations. Thaum lub kab yog thaum uas tig mus , tsis muaj kev daws teeb meem , thiab qee zaum ob qhov sib npaug yuav teeb tsa tib yam kab , yog li cas peb muaj tus naj npawb ntawm infinite kev daws teeb meem.
Tsis tas li ntawd, cov kab sib txuas puas muaj tib txoj kab nqes? Parallel kab muaj tib txoj kab nqes thiab yuav tsis sib tshuam. Parallel kab txuas ntxiv, lus, mus ib txhis tsis kov (xav tias cov no kab yog on ib yam dav hlau). Ntawm qhov tod tes, lub txoj kab nqes ntawm perpendicular kab yog cov tsis zoo reciprocals ntawm ib leeg, thiab ib khub ntawm no kab sib tshuam ntawm 90 degrees.
Kuj paub, nws puas tuaj yeem muaj ntau dua ib qho X Y khub uas yog kev daws teeb meem rau ob qho tib si?
Yog ob kab tshwm sim rau muaj tib txoj kab nqes, tab sis tsis yog tib txoj kab, ces lawv yuav tsis sib tshuam. Nyob ntawd yog tsis muaj khub ( x , y ) uas tuaj yeem txaus siab ob qho tib si sib npaug , vim nyob ntawd tsis muaj point ( x , y ) uas yog tib lub sijhawm ob leeg kab. Yog li cov no kev sib npaug tau hais tias tsis sib haum, thiab nyob ntawd yog tsis muaj daws.
Qhov kev daws teeb meem tsis kawg zoo li cas?
Thawj yog thaum peb muaj dab tsi hu ua kev daws teeb meem tsis kawg . Qhov no tshwm sim thaum txhua tus lej yog cov kev daws teeb meem . Qhov xwm txheej no txhais tau tias tsis muaj leej twg daws . Qhov sib npaug 2x + 3 = x + x + 3 yog ib qho piv txwv ntawm kev sib npaug uas muaj tsis kawg tus lej ntawm kev daws teeb meem.

Yuav ua li cas muaj ntau yam kev daws teeb meem overlapping kab?
Cov kab ke ntawm kab sib npaug tuaj yeem tsuas muaj 0, 1, lossis ib qho kev daws teeb meem tsis kawg. Ob kab no tsis tuaj yeem hla ob zaug. Cov lus teb raug yog tias qhov system muaj ib qho kev daws teeb meem. 2-Point Baskets Number of 3-Point Baskets 1 0 2 1 3 2 4 3
Muaj pes tsawg txoj kev nyob nruab nrab ntawm ob txoj kab ntsug?
Qhov no muab peb txoj hauv kev ntawm qhov chaw (A) thiab qhov chaw (E) vertex
Muaj pes tsawg txoj kev daws teeb meem yog linear equation?
Cov kab ke ntawm kab sib npaug tuaj yeem tsuas muaj 0, 1, lossis ib qho kev daws teeb meem tsis kawg. Ob kab no tsis tuaj yeem hla ob zaug. Cov lus teb raug yog tias qhov system muaj ib qho kev daws teeb meem
Puas yog nws ua tau rau ib qho kev sib npaug ntawm ob txoj kab sib npaug kom tsis muaj kev daws teeb meem piav qhia koj qhov laj thawj?
Cov kab ke ntawm kab sib npaug tuaj yeem tsuas muaj 0, 1, lossis ib qho kev daws teeb meem tsis kawg. Ob kab no tsis tuaj yeem hla ob zaug. Cov lus teb raug yog tias qhov system muaj ib qho kev daws teeb meem. Total Number of Points Number of 2-Point Baskets Number of 3-Point Baskets 17 4 (8 ntsiab lus) 3 (9 points) 17 1 (2 points) 5 (15 points)
Muaj pes tsawg txoj kev daws teeb meem muaj qhov system?
ib xal Ua raws li qhov no hauv kev txiav txim siab, pes tsawg txoj kev daws teeb meem puas muaj qhov sib npaug? Ib qho kev sib npaug ntawm cov kab sib npaug feem ntau muaj ib qho kev daws teeb meem, tab sis qee zaum nws tuaj yeem tsis muaj kev daws teeb meem (cov kab sib txuas) lossis cov kev daws teeb meem tsis kawg (tib kab).
