kev sib npaug tsis sib xws . npe. Kev sib npaug tsis sib xws txhais tau tias yog ob lossis ntau dua kev sib npaug uas yog tsis yooj yim sua kom daws tau raws li kev siv ib txheej ntawm qhov tseem ceeb rau qhov sib txawv. Ib qho piv txwv ntawm ib txheej kev sib npaug tsis sib xws x + 2 = 4x + 2 = 6. Koj Dictionary txhais thiab piv txwv kev siv.
Hais txog qhov no, lub ntsiab lus ntawm kev sib raug zoo thiab tsis sib haum yog dab tsi?
Txhais 1.5. 2 Qhov system ntawm kab zauv sib npaug yog hu ua tsis sib xws yog nws tsis muaj kev daws teeb meem. Lub kaw lus uas muaj kev daws teeb meem yog hu ua zoo ib yam . Yog ib qhov system tsis sib xws , REF tau los ntawm nws cov augmented matrix yuav suav nrog ib kab ntawm.
Tsis tas li ntawd, qhov piv txwv ntawm kev sib npaug tsis sib xws yog dab tsi? kev sib npaug tsis sib xws . npe. Kev sib npaug tsis sib xws txhais tau tias yog ob lossis ntau dua kev sib npaug uas yog tsis yooj yim sua kom daws tau raws li kev siv ib txheej ntawm qhov tseem ceeb rau cov variables. Ib piv txwv ntawm ib set ntawm kev sib npaug tsis sib xws x + 2 = 4x + 2 = 6.
Ntawm no, koj txhais li cas los ntawm kev tsis sib haum xeeb?
npe. tsis muaj kev sib haum xeeb ntawm qhov sib txawv lossis cov ntsiab lus; tus kheej tsis sib xws: ib tsis sib xws dab neeg. tsis muaj kev pom zoo, xws li ib yam nrog lwm tus lossis ob lossis ntau yam hauv kev sib raug zoo; ntawm variance: cov ntsiab lus uas yog tsis sib xws nrog rau cov lus qhia yav dhau los.
Yuav ua li cas koj txiav txim siab yog tias ib qho kev sib raug zoo tsis muaj kev daws teeb meem?
Yog ib qhov system muaj tsawg kawg yog ib qho daws , hais tias yog zoo ib yam . Yog a zoo ib yam system muaj raws nraim ib daws , nws yog ywj siab. Yog a zoo ib yam system muaj ib tug infinite xov tooj ntawm kev daws, nws yog nyob. Thaum koj kos cov kab zauv, ob qho tib si sib npaug sawv cev tib kab.

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
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)
Yuav ua li cas yog hais tias cov tshuaj sib npaug tsis sib npaug?
Yog tias qhov sib npaug ntawm cov tshuaj tsis sib npaug ces nws ua txhaum txoj cai lij choj ntawm Kev Tiv Thaiv MASS uas tau muab los ntawm Antoine Lavoiser, nws hais tias tus naj npawb ntawm cov atoms nyob rau sab reactant yuav sib npaug ntawm cov atoms nyob rau hauv cov khoom ntawm tib lub ntsiab los yog peb. tuaj yeem hais tias atoms tsis tuaj yeem rhuav tshem los yog ua tau
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
