A system ntawm equations yog sau los ntawm ob lossis ntau dua kev sib npaug nrog ib tug tib txheej ntawm tsis paub. Hauv kev daws teeb meem a system ntawm equations , peb sim nrhiav qhov tseem ceeb rau txhua qhov tsis paub uas yuav txaus siab rau txhua tus kev sib npaug hauv qhov system . Qhov teeb meem tuaj yeem hais qhia hauv daim ntawv piav qhia lossis qhov teeb meem tuaj yeem qhia hauv daim ntawv algebraic.
Tom qab ntawd, dab tsi yog qhov sib txawv ntawm cov kab ke sib npaug?
Muaj peb hom kev sib npaug ntawm cov kab sib npaug hauv ob qhov sib txawv, thiab peb hom kev daws teeb meem
- Ib qho kev ywj pheej muaj raws nraim ib qho kev daws teeb meem (x, y). Lub ntsiab lus uas ob kab sib tshuam yog tib txoj kev daws teeb meem.
- Ib qho kev tsis sib haum xeeb tsis muaj kev daws teeb meem.
- Ib tug dependent system muaj ntau infinitely daws.
Ib tug kuj nug, dab tsi yog 3 hom kab sib npaug? Muaj peb hom loj ntawm cov kab zauv sib npaug: taw tes - txoj kab nqes form, standard form, thiab txoj kab nqes - cuam tshuam daim ntawv.
Kuj nug, dab tsi yog 3 txoj hauv kev los daws cov kab ke sib npaug?
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.
Dab tsi yog qhov system ntawm equations los ntawm graphing?
daws systems ntawm equations los ntawm graphing . A qhov system ntawm linear kev sib npaug muaj ob lossis ntau dua kev sib npaug e.g. y = 0.5x + 2 y = x - 2. Kev daws ntawm xws li ib tug qhov system yog tus txiav txim khub uas yog kev daws rau ob leeg kev sib npaug . Txoj kev daws rau lub qhov system yuav nyob rau hauv qhov chaw uas ob kab sib tshuam.

Cov txheej txheem ntawm kev tsim cov kev daws teeb meem yog dab tsi?
Kev daws yog tsim thaum ib yam khoom hu ua thesolute 'dissolves' rau hauv lwm yam khoom hu ua hnyav.Dissolving yog thaum lub solute tawg los ntawm ib tug loj siv lead ua ntawm molecules mus rau ntau me me los yog ib tug molecules. Lawv ua qhov no los ntawm rub tawm cov ions thiab tom qab ntawd ncig cov ntsev molecules
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 tseem ceeb ntawm cov coefficients hauv kev sib npaug sib npaug?
Coefficients yog ib qho tseem ceeb los ua pov thawj txoj cai ntawm kev txuag ntawm huab hwm coj. Cov coefficients nyob rau hauv ib qho kev sib npaug ntawm cov tshuaj sib npaug qhia cov txheeb ze ntawm moles ofreactants thiab cov khoom. Los ntawm cov ntaub ntawv no, lub Cheebtsam ntawm reactants thiab cov khoom yuav raug xam. Koj tuaj yeem txiav txim seb tus lej ntawm moles ntawm cov khoom
Dab tsi yog cov txheej txheem ntawm kev sib txuas monomers los tsim cov saw ntev?
Feem ntau cov roj ntsha molecules loj heev thiab tsim los ntawm kev sib sau me me molecules, los yog monomers, rau hauv cov saw ntev. Cov txheej txheem ntawm kev sib txuas cov monomers, hu ua lub cev qhuav dej condensation, suav nrog kev tshem tawm ob lub atoms hydrogen thiab ib qho oxygen atom los tsim dej
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
