Thaum muab ob qhov sib npaug hauv ob variables, muaj qhov tseem ceeb ob txoj kev algebraic rau kev daws lawv. Ib qho yog kev hloov pauv, thiab lwm qhov yog tshem tawm.
Hais txog qhov no, dab tsi yog 2 txoj hauv kev los daws qhov kev sib npaug ntawm algebraically?
Muaj ob txoj kev uas yuav siv tau rau hauv zaj lus qhia no daws qhov system ntawm linear equations algebraically . Lawv yog 1) hloov, thiab 2 ) tshem tawm. Lawv yog ob qho tib si tsom rau kev tshem tawm ib qho kev sib txawv kom cov txheej txheem algebraic ib txwm siv tau rau daws rau lwm qhov sib txawv.
Tom qab ntawd, lo lus nug yog, qhov kev daws teeb meem algebraically txhais li cas? Cov algebraic txoj kev hais txog ntau txoj kev ntawm daws ib khub ntawm kab sib npaug, nrog rau cov duab kos, hloov pauv thiab tshem tawm.
Raws li txoj cai, 3 txoj hauv kev los daws cov kab ke sib npaug yog dab tsi?
Algebra 1 Txoj kev hloov Peb txoj kev uas feem ntau siv los daws cov kab ke sib npaug yog hloov pauv, tshem tawm thiab augmented matrices. Kev hloov pauv thiab tshem tawm yog txoj hauv kev yooj yim uas tuaj yeem daws tau ntau lub tshuab ntawm ob qhov sib npaug hauv ob peb kauj ruam yooj yim.
Yuav ua li cas koj daws ib qhov system ntawm equations graphically?
Kev daws ntawm xws li ib tug qhov system yog tus txiav txim khub uas yog kev daws rau ob leeg kev sib npaug . Rau daws qhov system ntawm linear equations graphically peb daim duab ob leeg kev sib npaug nyob rau hauv tib lub koom haum qhov system . Txoj kev daws rau lub qhov system yuav nyob rau hauv lub point uas ob kab sib tshuam.

Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Qhov sib npaug sib npaug rau qhov nruab nrab ntawm h2so4 los ntawm Koh yog dab tsi?
Hauv daim vis dis aus no peb yuav sib npaug ntawm qhov sib npaug KOH + H2SO4 = K2SO4 + H2O thiab muab cov coefficients raug rau txhua qhov sib xyaw. Txhawm rau sib npaug KOH + H2SO4 = K2SO4 + H2O koj yuav tsum nco ntsoov suav tag nrho cov atoms ntawm txhua sab ntawm cov tshuaj sib npaug
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)
Dab tsi yog qhov sib txawv ntawm cov kab lus sib npaug thiab qhov sib npaug sib npaug?
Cov kab lus sib npaug muaj qhov muaj txiaj ntsig zoo ib yam tab sis tau nthuav tawm nyob rau hauv ib hom ntawv sib txawv uas siv cov khoom ntawm cov lej xws li ax + bx = (a + b) x yog cov kab lus sib npaug. nruj me ntsis, lawv tsis yog 'sib npaug', yog li peb yuav tsum siv 3 kab sib luag hauv 'sib npaug' es tsis yog 2 raws li qhia ntawm no
