RULE #2: to txav los yog tshem tawm ib qho ntau los yog sib txawv on ib sab ntawm kev sib npaug , ua qhov " rov qab "ua haujlwm nrog nws ntawm ob sab ntawm kev sib npaug . Piv txwv li yog tias koj muaj g-1 = w thiab xav cais g, ntxiv 1 rau ob qho tib si sab (g-1+1 = w+1). Simplify (vim (-1 + 1) = 0) thiab xaus nrog g = w + 1.
Ib yam li ntawd, tib neeg nug, tus qauv hauv lej yog dab tsi?
Lub ntsiab txhais ntawm a qauv yog ib pab pawg lej cov cim uas qhia txog kev sib raug zoo los yog siv los daws qhov teeb meem, lossis ib txoj hauv kev los ua ib yam dab tsi. Ib pawg ntawm lej cov cim uas qhia txog kev sib raug zoo ntawm ib ncig ntawm lub voj voog thiab nws txoj kab uas hla yog ib qho piv txwv ntawm a qauv.
Kuj Paub, coefficients yog dab tsi? Hauv lej, a coefficient yog ib qho kev sib txuam hauv qee lub sij hawm ntawm polynomial, series, lossis ib qho kev qhia; nws feem ntau yog tus lej, tab sis tej zaum yuav yog ib qho kev qhia. Piv txwv li, yog tias y raug suav tias yog ib qho parameter hauv cov lus hais saum toj no, qhov coefficient ntawm x yog −3y, thiab qhov tsis tu ncua coefficient yog 1.5 + y.
Kuj Paub, koj puas tuaj yeem muab ob sab ntawm qhov sib npaug los ntawm qhov sib txawv?
Multiplication Khoom Vaj Huam Sib Luag Yog tias ob qho kev qhia sib npaug thiab koj multiply ob sab los ntawm tib tus lej, cov lus qhia tshwm sim yuav kuj ua sib npaug. Thaum lub kev sib npaug koom nrog kev sib npaug los yog faib, koj ua tau "undo" cov haujlwm no los ntawm kev siv cov haujlwm inverse los cais cov sib txawv.
Yuav ua li cas koj rearrange acceleration equation?
Kev nrawm yog tus nqi ntawm kev hloov ceev ntawm ib yam khoom. wo ib kev ceev , v yog qhov kawg tshaj tawm ntawm cov khoom, u yog qhov pib tshaj tawm ntawm cov khoom thiab t yog lub sijhawm uas tau dhau mus. Qhov no kev sib npaug tuaj yeem yog rov kho dua muab: v = u + at.

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
Nws puas yuav ua rau pom qhov sib npaug ntawm kab sib npaug mus rau ib kab thiab los ntawm ib qho taw tes ntawm kab?
Qhov sib npaug ntawm ib kab uas yog parallel lossis perpendicular rau ib kab? Cov lus teb tau: Cov nqes hav ntawm cov kab sib npaug sib npaug. Hloov txoj kab nqes paub thiab cov kev sib koom ua ke ntawm ib qho taw tes ntawm lwm txoj kab rau hauv daim ntawv point-slope kom pom qhov sib npaug ntawm kab 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
