Cov txheej txheem ntawm linear equations tau xwb muaj 0, 1, lossis tus lej tsis kawg kev daws teeb meem . Cov no ob kab tsis tuaj yeem hla ob zaug. Cov cov lus teb yog qhov ntawd qhov system muaj ib daws.
| Tag Nrho Cov Ntsiab Lus | Tus naj npawb ntawm 2-Point Baskets | Tus naj npawb ntawm 3-Point Baskets |
|---|---|---|
| 17 | 4 (8 ntsiab lus) | 3 (9 ntsiab lus) |
| 17 | 1 (2 ntsiab lus) | 5 (15 ntsiab lus) |
Tsis tas li lo lus nug yog, nws puas tuaj yeem ua rau lub kaw lus ntawm ob kab sib npaug tsis muaj kev daws teeb meem?
Qhov system ntawm Linear Equations nrog Tsis muaj kev daws teeb meem Thaum twg ob qhov sib npaug muaj tib txoj kab nqes tab sis txawv y-axis, lawv yog parallel. Txij li thaum ob qhov sib npaug yeej tsis sib tshuam, lub qhov system muaj tsis muaj kev daws teeb meem.
dab tsi system ntawm equations tsis muaj kev daws teeb meem? Ib qho tsis sib xws system ntawm equations yog a system ntawm equations nrog tsis muaj tshuaj . Peb tuaj yeem txiav txim siab yog tias peb qhov system yog inconsistent nyob rau hauv peb txoj kev: graphing, algebra, thiab logic. Graphs ntawm qhov tsis sib xws qhov system yuav muaj tsis muaj cov ntsiab lus ntawm kev sib tshuam.
Ib yam li ntawd, tib neeg nug, puas muaj peev xwm muaj qhov sib npaug uas tsis muaj kev daws teeb meem?
Yog tias ob kab tshwm sim muaj tib txoj kab nqes, tab sis tsis yog tib txoj kab, ces lawv yuav tsis sib tshuam. Nyob ntawd yog tsis muaj khub (x, y) uas yuav txaus siab rau ob leeg kev sib npaug , vim nyob ntawd yog tsis muaj point (x, y) uas yog ib txhij ntawm ob kab. Yog li cov no kev sib npaug tau hais tias tsis sib haum, thiab nyob ntawd yog tsis muaj tshuaj.
Koj yuav daws tau qhov system ntawm kev sib npaug li cas?
Ua raws li cov kauj ruam los daws qhov teeb meem
- Kauj Ruam 1: Muab tag nrho thawj qhov sib npaug los ntawm 2.
- Kauj Ruam 2: Rov sau cov txheej txheem ntawm kev sib npaug, hloov thawj qhov sib npaug nrog cov kab zauv tshiab.
- Kauj Ruam 3: Ntxiv qhov sib npaug.
- Kauj ruam 4: daws rau x.
- Kauj Ruam 5: Nrhiav y-tus nqi los ntawm kev hloov hauv 3 rau x hauv qhov sib npaug.

Puas yog nws ua tau rau ob kab equipotential hla ob txoj kab hluav taws xob piav qhia?
Equipotential kab ntawm cov peev txheej sib txawv tuaj yeem tsis hla ib qho. Qhov no yog vim hais tias lawv yog, los ntawm kev txhais, ib txoj kab ntawm lub peev xwm tas li. Lub equipotential ntawm ib qho chaw hauv qhov chaw tuaj yeem tsuas muaj ib qho nqi xwb. Lus Cim: Nws yog ua tau rau ob kab sawv cev tib lub peev xwm hla
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
Qhov laj thawj twg zoo tshaj plaws piav qhia vim li cas cov hlau tsis muaj ductile es tsis nkig?
Cov hlau yog ductile es tsis txhob nkig vim tias lawv muaj cov ntawv cog lus hloov tau. Ductility txhais tau hais tias muaj peev xwm ntawm cov hlau los kos rau hauv cov xov hlau. Cov hlau muaj cov khoom sib txuas yooj yim. Qhov kev hloov pauv no tso cai rau lawv ua cov khoom siv
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
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
