Piav: A kab perpendicular rau y axis yuav yog kab rov tav kab , cov kev sib npaug ntawm tej kab rov tav kab yog y = b qhov twg b yog tus y - cuam tshuam.
Hais txog qhov no, txoj kab nqes ntawm txoj kab uas yog perpendicular rau Y axis yog dab tsi?
Cov y - axis yog a kab ntsug . A kab ntsug muaj ib txoj kab nqes ntawm 10 uas yog undef lossis undefined. Qhov tsis zoo yuav yog 01 lossis 0. Yog li, cov txoj kab nqes ntawm perpendicular yuav 0.
Ib yam li ntawd, qhov sib npaug ntawm kab sib npaug rau y axis yog dab tsi? Yog li, yog tias P(x, y) yog ib qho taw tes AB, x = a. Yog li, qhov sib npaug ntawm txoj kab ncaj nraim mus rau y-axis ntawm a nyob deb los ntawm nws yog x = a. Qhov sib npaug ntawm y-axis yog x = 0, vim, y-axis yog ib qho sib npaug rau nws tus kheej ntawm ib qho nyob deb 0od nws.
Yog li ntawd, dab tsi yog perpendicular rau Y axis?
Cov kab yog perpendicular mus rau y - axis txhais tau hais tias nws yog kab rov tav los yog parallel rau x- axis , txhais tau tias txoj kab nqes (m) = 0.
Yuav ua li cas koj sau ib qho kev sib npaug rau ib kab perpendicular?
Ua ntej, muab tso rau kev sib npaug ntawm kab muab rau hauv daim ntawv nqes hav-intercept los ntawm kev daws rau y. Koj tau txais y = 2 x + 5, yog li txoj kab nqes yog -2. Perpendicular kab muaj opposite-reciprocal slopes, yog li txoj kab nqes ntawm lub kab peb xav nrhiav yog 1/2. Plug nyob rau hauv lub point muab rau hauv lub kev sib npaug y = 1/2 x + b thiab daws b, peb tau b = 6.

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 sib npaug sib npaug rau qhov nruab nrab ntawm h2so4 los ntawm Koh yog dab tsi?
Hauv daim vis dis aus no peb yuav sib npaug ntawm qhov sib npaug KOH + H2SO4 = K2SO4 + H2O thiab muab cov coefficients raug rau txhua qhov sib xyaw. Txhawm rau sib npaug KOH + H2SO4 = K2SO4 + H2O koj yuav tsum nco ntsoov suav tag nrho cov atoms ntawm txhua sab ntawm cov tshuaj sib npaug
Dab tsi yog qhov sib txawv ntawm qhov sib txawv ntawm cov kab sib txuas thiab ntau qhov sib piv?
6. (2 lub cim) Qhov sib txawv ntawm cov kab sib txuas (kev sib piv) thiab ntau qhov sib piv yog dab tsi? Cov kab sib xyaw ua ke yog npaj sib piv; uas yog, tshwj xeeb txhais tau tias yog ua ke nyob rau hauv ntau txoj kev thiab contrasted nrog rau lwm yam kev sib txuas ntawm txhais tau tias
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
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
