Kev nthuav qhia thiab kev sib npaug . Ib kev qhia yog tus lej, qhov sib txawv, lossis kev sib txuas ntawm cov lej thiab qhov sib txawv thiab cov cim ua haujlwm. Ib kev sib npaug yog ua los ntawm ob cov lus qhia txuas los ntawm kev sib npaug.
Tsis tas li ntawd, kev qhia lej txhais li cas?
Ib kev qhia yog ib kab lus uas muaj tsawg kawg yog ob tus lej thiab tsawg kawg yog ib qho lej kev ua haujlwm. Qhov no lej kev ua haujlwm tuaj yeem yog qhov sib ntxiv, rho tawm, sib npaug, thiab faib. Structure ntawm ib kev qhia yog: Kev nthuav qhia = (Ntau, lej Tus neeg teb xov tooj, tus xov tooj)
Ib tug kuj yuav nug, dab tsi yog piv txwv ntawm cov lus? Lub ntsiab txhais ntawm ib qho piv txwv ntawm kev qhia yog ib lo lus uas nquag siv los yog kab lus los yog nws yog ib txoj hauv kev los qhia koj cov kev xav, kev xav lossis kev xav.
- Ib qho piv txwv ntawm ib qho kev qhia yog kab lus "ib qho nyiaj tau txais txiaj ntsig yog ib qho nyiaj tau los."
- Ib qho piv txwv ntawm kev qhia yog kev luag.
Tom qab ntawd, qhov sib npaug yog dab tsi?
Ib kev sib npaug yog ib nqe lus lej uas ob yam sib npaug. Nws muaj ob kab lus, ib qho ntawm txhua sab ntawm ib qho 'equals' kos npe. Piv txwv li: 12.
Lub ntsiab txhais ntawm kev ntsuam xyuas ib qho kev qhia yog dab tsi?
Rau ntsuas ib algebraic kev qhia , koj yuav tsum hloov tus lej rau txhua qhov sib txawv thiab ua cov lej lej. Yog tias peb paub tus nqi ntawm peb qhov kev hloov pauv, peb tuaj yeem hloov pauv qhov hloov pauv nrog lawv cov txiaj ntsig thiab tom qab ntawd ntsuas tus kev qhia.

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
Puas yog txhua qhov sib npaug sib npaug sib npaug?
Thawj qhov sib npaug sib npaug yog qhov tseeb yog tias nws muaj kev txuag kom muaj nuj nqis. Piv txwv li, qhov sib npaug sib cais yeej ib txwm muaj tseeb, txij li lub ntsiab lus lawv yog ntawm daim ntawv: M(y) + N(t) = 0, yog li ϕ(t, y) = A(y) + B(t) yog a khaws cia kom muaj nuj nqis
Cov coefficients hauv kev sib npaug tshuaj sib npaug qhia koj li cas txog cov reactants thiab cov khoom?
Cov coefficients ntawm kev sib npaug chemicalequation qhia peb cov txheeb ze ntawm moles ntawm reactants thiab cov khoom. Hauv kev daws teeb meem stoichiometric, kev hloov pauv ntawm moles ntawm reactants rau moles ntawm cov khoom raug siv. Hauv kev suav loj, cov molar loj yog xav tau los hloov cov huab hwm coj mus rau moles
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
