Muaj peb kauj ruam:
- Rearrange tus kev sib npaug yog li "y" nyob rau sab laug thiab txhua yam ntawm sab xis.
- Teem lub "y = kab" (ua rau nws yog ib txoj kab ruaj khov rau y≤ lossis y≥, thiab ib kab dashed rau y)
- Duab ntxoov ntxoo saum kab rau "ntau dua" (y> lossis y≥) lossis hauv qab kab rau "tsawg dua" (y< lossis y≤).
Yog li ntawd, koj yuav ua li cas daws ib qho kev tsis sib xws?
Kev daws qhov tsis sib xws ntawm ib leeg ua raws li zoo tib yam txheej txheem rau daws linear kev sib npaug. Peb yuav ua kom yooj yim rau ob sab, tau txais tag nrho cov ntsiab lus nrog qhov sib txawv ntawm ib sab thiab cov lej ntawm lwm sab, thiab tom qab ntawd muab faib / faib ob sab los ntawm coefficient ntawm qhov sib txawv kom tau txais kev daws teeb meem.
Tom qab ntawd, lo lus nug yog, lub ntsiab lus ntawm linear inequality yog dab tsi? Los ntawm Wikipedia , phau ntawv dawb encyclopedia. Hauv lej a linear tsis sib xws yog ib kev tsis sib xws uas koom nrog a kab tawm muaj nuj nqi. A linear tsis sib xws muaj ib lub cim ntawm kev tsis sib xws :. Nws qhia cov ntaub ntawv uas tsis sib npaug hauv daim duab.
Nyob rau hauv no, dab tsi yog ib qho piv txwv ntawm ib tug linear inequality?
Piv txwv 1: Graph ua linear tsis sib xws y > 2x − 1. Graph the line y = 2x – 1 in the xy axis using your preferred method. Txij li thaum kev tsis sib xws lub cim tsuas yog loj dua ">", thiab tsis ntau dua lossis sib npaug rau "≧", txoj kab ciam teb yog dotted lossis dashed.
Dab tsi yog linear inequality thiab piv txwv?
Linear tsis sib npaug hauv ob qhov sib txawv. Qhov kev daws teeb meem ntawm a linear tsis sib xws Hauv ob qhov sib txawv xws li Ax + Los ntawm> C yog ib khub xaj (x, y) uas tsim cov lus tseeb thaum cov txiaj ntsig ntawm x thiab y raug hloov mus rau hauv kev tsis sib xws . Piv txwv . Yog (1, 2) kev daws teeb meem rau cov kev tsis sib xws . 2x + 3y> 1.

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 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)
Vim li cas koj tig lub cim tsis sib xws thaum koj sib npaug lossis faib los ntawm qhov tsis zoo?
Thaum koj muab ob sab los ntawm tus nqi tsis zoo koj ua rau sab uas ntau dua muaj 'loj' tus lej tsis zoo, uas txhais tau tias tam sim no tsawg dua lwm sab! Qhov no yog vim li cas koj yuav tsum tig lub cim thaum twg koj muab los ntawm tus lej tsis zoo
Koj yuav daws qhov kev sib npaug lossis qhov tsis sib xws li cas?
Txhawm rau daws qhov tsis sib xws siv cov kauj ruam hauv qab no: Kauj Ruam 1 Tshem tawm cov feem ntau los ntawm kev muab tag nrho cov ntsiab lus los ntawm tus lej qis tshaj ntawm txhua feem. Kauj Ruam 2 Ua kom yooj yim los ntawm kev sib txuas zoo li cov ntsiab lus ntawm txhua sab ntawm qhov tsis sib xws. Kauj Ruam 3 Ntxiv lossis rho tawm kom tau txais qhov tsis paub ntawm ib sab thiab tus lej ntawm lwm qhov
Yuav ua li cas koj thiaj paub yog tias tus nqi tsis sib xws tsis muaj kev daws teeb meem?
Okay, yog tias qhov tseem ceeb tshaj plaws yeej ib txwm zoo lossis xoom tsis muaj txoj hauv kev uas lawv tuaj yeem tsawg dua lossis sib npaug rau tus lej tsis zoo. Yog li ntawd, tsis muaj kev daws teeb meem rau ob qho no. Hauv qhov no yog tias tus nqi tiag tiag yog qhov zoo lossis xoom ces nws yuav nco ntsoov ntau dua lossis sib npaug rau tus lej tsis zoo
