SOLVING EQUATIONS CONTAINING ABSOLUTE VALUE(S)
- Kauj ruam 1: cais cov tus nqi kiag kev qhia.
- Kauj ruam 2: Teem kom muaj nuj nqis hauv lub tus nqi kiag notation sib npaug rau + thiab - qhov ntau ntawm lwm sab ntawm lub kev sib npaug .
- Kauj Ruam 3: daws rau qhov tsis paub hauv ob qho tib si kev sib npaug .
- Kauj Ruam 4: Tshawb xyuas koj cov lus teb analytically lossis graphically.
Ntawm no, koj yuav ua li cas daws cov nqi sib npaug thiab qhov tsis sib xws?
Koj pib los ntawm kev ua nws ua ob qho sib cais kev sib npaug thiab tom qab ntawd daws lawv cais. Ib tus nqi sib npaug tsis muaj kev daws teeb meem yog tias cov tus nqi kiag kev qhia sib npaug ntawm tus lej tsis zoo txij li ib tus nqi kiag yeej tsis tuaj yeem ua tsis zoo. Koj tuaj yeem sau ib qho tus nqi tsis sib xws raws li kev sib xyaw kev tsis sib xws.
Tsis tas li ntawd, tus nqi tiag tiag rau 4 yog dab tsi? Tus nqi kiag piav qhia qhov kev ncua deb ntawm tus lej ntawm tus lej kab ntawm 0 yam tsis xav txog qhov kev taw qhia ntawm xoom tus lej dag. Cov tus nqi kiag ntawm tus lej yeej tsis muaj qhov tsis zoo. Cov tus nqi kiag 5 yog 5.
Yog li ntawd, dab tsi yog cov cai rau tus nqi tiag?
Thaum peb muab lub tus nqi kiag ntawm tus lej, peb ib txwm xaus nrog tus lej zoo (lossis xoom). Txawm hais tias qhov kev tawm tswv yim yog qhov zoo lossis tsis zoo (lossis xoom), cov zis yog ib txwm zoo (lossis xoom). Piv txwv li, | 3 | = 3, thiab | –3 | = 3 too.
Tus nqi ntawm 3 yog dab tsi?
Piv txwv li, lub tus nqi kiag li ntawm 3 yog 3 , thiab cov tus nqi kiag ntawm - 3 kuj yog 3 . Cov tus nqi kiag ntawm tus lej yuav xav tias nws nyob deb ntawm xoom.

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)
Koj yuav daws qhov sib npaug li cas los ntawm kev cais qhov sib txawv?
Cov txheej txheem yooj yim los cais qhov sib txawv yog "ua ib yam dab tsi rau ob tog" ntawm qhov sib npaug, xws li ntxiv, rho tawm, sib npaug, lossis faib ob sab ntawm qhov sib npaug los ntawm tib tus lej. Los ntawm kev rov ua cov txheej txheem no, peb tuaj yeem tau txais qhov sib txawv ntawm ib sab ntawm qhov sib npaug
Dab tsi yog ob txoj hauv kev los daws qhov kev sib npaug ntawm algebraically?
Thaum muab ob qhov sib npaug hauv ob qhov sib txawv, muaj ob txoj hauv kev algebraic los daws lawv. Ib qho yog kev hloov pauv, thiab lwm qhov yog tshem tawm
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
