Math Question!!!!

[miamichico]

LOL, well i know this is WAY OFF topic but i cant figure this out, ITS DRIVING ME CRAZY .

x (to the -3Power) divided by y (to the -4 Power) anyone anyone????

I've been trying to figure this shit out and cant, i hate MaTh!!!!!!!

lol thank you guys, peace!!!!!!!

what are you trying to accomplish? what do you want to do the equation?

that is the same thing as x^-3/y^-4=y^4/x^3

[maximo61170]

? its equiv to y^4/x^3

[maximo61170]

ha yea. there really is no question....

[miamichico]

is a quesiton im trying to answer for school that i cant figure out.

it says, "use the properties of exponents to simplify x^(-3 power) divided by y^(-4 power).

a) x^(4) over y^(3)

b) (xy) -3/4

c) (xy) 3/4

d) x^(3)y^(4)


I think its A. I think all you have to do is flip the powers and reverse the negatives to positives. SOrry guys just hoping i can get some help since i suckkkkkkkkkkk at math.


OH SHITTTTT """""""""""""MIX and MAXIMO U GUYS R THE SHIT!!!!!!!!!!!"""""""""""""""""" I JUST SAW UR ANSWER IT SOUNDS RIGHTTTTTT TO WHAT I PUT DOWN, WHAT A RELIEF! thank you guys and sorry for the stupid post lol.

Well while im here i might as well say i think them se-r spec v owners have alot of respect for us, especially for Hondata. i went snooping into my specv.com the other day and they love to race 8thgen SI but no matter what, they say that after 3rd-4th the si always pull on them, and as per hondata they wish they had a little something like. Man i haven't gotten my Si yet, im still saving up but cant wait, its good to know what your planning to get urself into sometime. Well thanks again guys, take care. Keep talking about math if you would like cuz ill be listening. Peace!

[miamichico]

Alright guys i need help with one more. SORRRRRRRYYYY! yall the shiznet though.

y^2+7y+10 over y^2+5y divided by y^2+y-2 over 2y


Thank You 8thGenMathematicians!!!!!!!!!!!!!!

[dc5jimbo]

ahah even when i was in school i failed math so yea sorry

xy+g23 wtf is this shittt

[maximo61170]

2/y-1

Ring Ring RIng Maximo u win the golden basket holding a nice turbo kit for ur ride (ill holla at you when i win the lottery or get rich with a nice future JOB) thanks man i really appreciate it, i was thinking about buying me a scientific calculator, forgot =( thanks my brotha i appreciate your help alot!!!!!!!!!

[maximo61170]

now do you know HOW im getting these and are too lazy to do it? or are you totally lost cuz i could post my work

[maximo61170]

you dont need a scientific calc to do this.

[miamichico]

yeaaaa man please post it cuz im LOST!!!!!!!!!!!!!!!!!!!!!!!!!! thank you sirrrrr

[miamichico]

hey by any chance can you show me a graph for this? 4x <= 5y-20??? lol man who ever thought this post was ever gonna come up here. lol i feel like an idiot but hey im learning, thanks again guys i really appreciate it.

[maximo61170]

so with what you posted...

when you divide 2 fractions, its the same thing as multiplying the top, by the reciprocal of the bottom. the reciprocal is just the fraction, flipped. for example, the reciprocal of 2/3 is 3/2.

so when you multiply the top by the recip. of the bottom, it becomes,
2y(y^2+7y+10) all over (y^2+5y)(y^2+y-2)

now you can factor (y^2+7y+10) to become (y+5)(y+2)
and (y^2+y-2) becomes (y+2)(y-1)
you can also pull out a y from (y^2+5y) to become y(y-5)

so it now becomes...
2y(y+5)(y+2) all over y(y-5)(y+2)(y-1)

then you can cancel things out because they equal 1. the two (y+5)s turn into one or cancels out, the (y+2) cancels out, and the y's (2y and y) cancel out to leave...

2/(y-1)

Thanks again Max, im going to go over it to make sure that i have learned it correctly. Any thoughts on the other i just posted? Thank you sir, holla! Let me know when show of of the month starts so i can nominate you man, cause this is helping me alot. We should grant a community service award hon this site cause damn everyone here is very helpfull. Thank agaon Max ur da shit brotha. Funny thing i my moms is here next to me and she's finding this website cool as well.

solve it for y. add 20 to both sides. then divide it by 5 for both sides. if you divide by a negative number, you have to change <= to >= but you dont so you can keep it how it is.

when you solve for y you get 4/5x+4<=y
then you compare it to y=mx+b, where m is your slope, and b is your yintercept

so (0,4) is a point then you rise 4 and run 5

k. you should be able to do the rest of your hw cuz i explained it a lot. aka... im not trying to do all your hw but i will help you.

[maximo61170]

then you pick a point that doesnt hit the line. like 0,0... if you can. if it agrees with the equation, then shade that area. if it doesn't, then shade the other portion of the graph
