Ua ntej, sau tus kev faib ua feem , siv ib tsab ntawv los sawv rau lub sij hawm uas ploj lawm. Peb pom cov khoom ntoo khaub lig los ntawm kev muab 20 npaug x, thiab 50 npaug ntawm 30. Ces faib mus nrhiav x. Kawm cov kauj ruam no kom ze, vim qhov no yog cov txheej txheem peb yuav siv ntau zaus hauv algebra.
Tom qab ntawd, peb txoj hauv kev koj tuaj yeem daws qhov kev faib ua feem yog dab tsi?
Peb txoj kev los daws cov proportions
- Ntsug.
- Kab rov tav.
- Diagonal (feem ntau hu ua "cross-products")
Tom qab ntawd, lo lus nug yog, dab tsi yog lub ntsiab lus ntawm kev faib ua feem? Synonyms : seem, dimension, counterbalance, ratio, symmetry, equaliser, residual, tshuav, counterpoise, residuum, so, counterweight, residue, tshuav log, equilibrium, symmetricalness, equipoise, ntawv, equalizer, proportionality . Antonyms: kev tsis sib haum. kev faib ua feem (lus qhia)
Ib tug kuj yuav nug, dab tsi yog tus qauv rau kev faib ua feem?
A kev faib ua feem tsuas yog ib nqe lus hais tias ob qhov sib npaug. Nws tuaj yeem sau tau ob txoj hauv kev: raws li ob qhov sib npaug sib npaug a / b = c / d; los yog siv ib tug nyuv, a:b = c:d. Hauv qab no kev faib ua feem yog nyeem li "nees nkaum yog rau nees nkaum-tsib li plaub yog rau tsib."
Dab tsi yog proportional thiab piv txwv?
A kev faib ua feem yog tiag tiag ob qhov piv txwv uas sib npaug rau ib leeg. Ntawm no yog ib qho piv txwv : Yog li ntawd, lawv yuav tsum tsim ib kev faib ua feem . 3rd txoj kev: Hla cov khoom: Muab cov lej uas muaj kab pheeb ces kaum rau ib leeg. Yog tias cov khoom sib npaug, ob qho piv txwv tsim a kev faib ua feem.

Yuav ua li cas koj nrhiav tau qhov kev daws teeb meem rau ib khub xaj?
Txhawm rau txheeb xyuas yog tias tus khub txiav txim yog qhov kev daws teeb meem rau qhov sib npaug, koj tuaj yeem ua qhov kev sim. Txheeb xyuas qhov x-tus nqi hauv tus khub xaj thiab ntsaws rau hauv qhov sib npaug. Thaum koj ua kom yooj yim, yog tias tus y-tus nqi koj tau txais yog tib yam li y-tus nqi hauv tus khub xaj, ces tus khub txiav txim yog qhov kev daws teeb meem rau qhov sib npaug
Koj yuav daws qhov teeb meem txoj kab nqes li cas?
Txheeb xyuas txoj kab nqes, m. Qhov no tuaj yeem ua tiav los ntawm kev suav cov nqes hav ntawm ob lub ntsiab lus ntawm txoj kab uas siv cov qauv nqes hav. Nrhiav y-intercept. Qhov no tuaj yeem ua tau los ntawm kev hloov txoj kab nqes thiab cov kev sib koom ua ke ntawm qhov taw tes (x, y) ntawm txoj kab hauv txoj kab nqes-intercept formula thiab tom qab ntawd daws rau b
Yuav ua li cas koj daws qhov limiting reactant loj teeb meem?
Nrhiav qhov txwv reagent los ntawm kev xam thiab sib piv cov khoom ntawm txhua reactant yuav tsim. Sib npaug cov tshuaj sib npaug rau cov tshuaj tiv thaiv. Hloov cov ntaub ntawv muab rau hauv moles. Siv stoichiometry rau txhua tus neeg reactant kom pom qhov loj ntawm cov khoom tsim
Koj yuav txiav txim siab li cas yog tias qhov tsis sib xws tsis muaj kev daws teeb meem?
Cais tawm tus nqi tseeb ntawm sab laug ntawm qhov tsis sib xws. Yog tias tus lej ntawm sab nraud ntawm qhov tsis sib xws yog qhov tsis zoo, koj qhov kev sib npaug tsis muaj kev daws teeb meem lossis tag nrho cov lej tiag tiag li kev daws teeb meem. Siv cov cim ntawm txhua sab ntawm koj qhov tsis sib xws los txiav txim siab qhov twg ntawm cov xwm txheej no tuav
Koj yuav daws qhov teeb meem li cas nrog 3 qhov sib txawv?
Ntawm no, nyob rau hauv cov kauj ruam hom ntawv, yog yuav ua li cas los daws qhov system nrog peb qhov sib npaug thiab peb qhov sib txawv: Xaiv ob khub ntawm qhov sib npaug ntawm qhov system. Tshem tawm tib qhov sib txawv los ntawm txhua tus khub siv txoj kev Ntxiv / rho tawm. Kev daws cov txheej txheem ntawm ob qhov sib npaug tshiab siv txoj kev Ntxiv/Subtraction
