Algebra 2 - Direct and Inverse Variation

Word problems? Ugh. Enter the world of YAY MATH which we break down these kinds of variation problems to that relieving phrase, "oh, it's not that bad..." So we're talking about direct variation, inverse variation, and joint variation. Oh, and for fun, notice I can erase the board by blowing on it... YAY MATH!
Learning should always be fun and connective. Please visit www.yaymath.org for:

[@greenlizardballs]

this guy talks to you like a person my math professor made all this sound so complicated many many thanks, yaymath

[@karlphilippalses1086]

It really helps me a lot. Before, I sucked at Math and now, many people considered me a Math Wizard. Thank you for making that happen.

[@josephmesina3975]

raise your hand if you also want him as your math teacher!! Yeaahhh!

[@sids5681]

[@viewingchannel101]

10 years later, you're still helping and inspiring students. Thank you, yaymath!

[@jaykae.x]

I was struggling to understand this in class cause my math teacher is so confusing😭But after watching this video i really understand it 🥳Thank you so much!!

[@samanthalava44]

Never mind. It is on his site under algebra 2 with the same title as this one. u click on it and it brings u to youtube with the same video but with 12 minutes instead of 8. aka full version

[@jaxbeetle]

this guy is making learning easy (and fun) for me, bless him, im binge studying these videos for my final

[@Pr_xity]

How it go?

[@nott.haseeb]

I learned and had fun listening to him. If every teacher was like him we would all love math

[@tripletish]

thanks so much for explaining this in a light and simple manner!

[@KirklandsKnowBest]

"Then get over that hump boo!" Lmao I love him!

[@TamakiCherry]

That was hilarious

[@KirklandsKnowBest]

TamakiCherry lol right? I wish I had him for a teacher

[@sumeraarshad3897]

"They can't spell constant" My thoughts exactly

[@misky9721]

I often hate math..but this guy.. you're like learning with ease

[@khaledhisham149]

i wish i have you as my teacher

[@leah8217]

Don't we all :)

[@supasayin4]

[@zehradilarakaradeniz7953]

[@keriannee]

[@alisheikh4003]

Hi beautiful lady

[@jenermorales6027]

[@melange6631]

[@omarmajed6800]

Thanks a lot sir, may may god bless you. This was so helpful, I have a final exam tomorrow and my problem was with this lesson.

[@knechtpayton12]

[@sweetpea2788]

I’ve never had a bad math teacher until junior year of high school. I’m good at math, but for some reason I can NOT understand my teacher (no one can lol) you’ve saved me

[@TheHouseElf]

Please come teach me math. All the time. Not only do I get what's going on now, but I actually enjoyed the lesson. THANK YOU SO MUCH.

[@d8nya1]

I wish I had a teacher like him

[@KubuntuYou]

We never covered half this stuff in my high school algebra ii class.

[@somarashed7895]

Really hope this man is doing well

[@jessicamentus6753]

That was fun,😊,i literally love this guy,i came thinking this is hard,now I actually learned alot.

[@doylebros9]

well, the way i look at it is something related to finding the LCD in an equation. say you had y= 6 (1/3). to factor out a fraction in a linear equation, you would find how many times 3 goes into 6. 3 goes into 6 2 times, so the 3 and 6 cancel, and youre left with a 2. so, y = 6 (1/3), y= 2.

[@gabyparra8199]

Youre really good at teaching! Thank you!

[@alisheikh4003]

Hi beautiful lady

[@queenofthepath]

I really LOVE this. Finally understand. Thank YOU! ;D :D

[@Iwantkababnow]

thanks now i know the difference!

[@princessmikuhatsune2450]

THANK YOU SO MUCH!!! I OWE YOU BIG TIME!!!

[@CookedAndBurnt]

question how did our teacher solved this can you help? When y varies inversely as x and y=14 when x=5, what is the value of x when y=4? a. x=15 b. x=20 c. x=12 d. x=10

[@nicolaszeballos7662]

Entendi en 11 minutos todo lo que no entendi en 1 mes. Thank you bro.

[@tharkrish]

[@darkwlfwr4430]

[@sukritgill8510]

[@thatFellowTraveler]

I notice that Robert is less tolerant of tom foolery in this video than in the prior lessons. Is there any reason for that?

[@Kevin-kv6bd]

wait this is what I'm learning right now and i'm in Algebra 1

[@sabrinahhkills07]

why do you use a different equation? the one i was told to use is y=k(1/x) or are they both the same?

[@imalbanian3235]

you are awesome i wish my teachers were like you

[@trishatalig]

omg, you teacher better then my teacher, thank you so much! (:

[@africankiwi1]

[@le_art3st875]

dope math teacher lit

[@rjenerlss2245]

our teacher doesnt let us use calculator :(

[@Breyerlover4ever23]

lol I hope your teacher allows you to use a calculator when you get to trigonometric ratios.

[@joshtran6689]

same here, he gets frustrated when we do 2-7

[@v5in88]

I mean, I ain't a smartass here but the reason why some or most of our math teachers won't let us use calculators is because they're trying to train our "second calculator" (our brains basically) and I know most of us or some of us are quite (no offence) slow at doing some simple maths and stuff but hey you know what they say, " slowly, but surely "

[@sushantpandit3434]

1st question is answer 8
