Question

PLEASE HELP ASAP I DONT GET IT O.o
find the value of y for a given value of x, if y varies directly with x if y=6 x=2, what is y when x=5
explain it in steps

Answer 1

6/2 = y/5
y = 15

Answer 2

If y varies directly to x then 6/2 = 3
I think that if x = 5 then y would be equal to 15

What do you think @ranga

Answer 3

Yes. 15.

Answer 4

@rockstargirl17 do you understand what I tried to explain?

Answer 5

yes and no so wait that means the answer is 15 im confused

Answer 6

Well see because y varies directly to x, that means that if you divide 6/2 it is equal to 3

so if you were trying to find y when x = 5 you multiply by 3

5 * 3 = 15

So yes the answer is 15 :)

Answer 7

oh okay i get it thank you very much :) could you help me with another problem im stuck on this one too :P

Answer 8

Sure

Answer 9

okay so it says
Divid -2x^3+21x^2-20x-12 by (x-3)

Answer 10

how exactly are you supose to do that :P

Answer 11

Divide?

Answer 12

yeah i know that but how would you divid it like do you just combine like terms or what

Answer 13

What grade is this for? I wouldn't combine like terms because their exponents are different.

Answer 14

11th

Answer 15

9th :<

I'd put the fraction over a common denominator.

-2(x-3)x^3/x-3 + 21(x-3)x^2/x-3 - 20(x-3)x - 12/x-3

Answer 16

:( hmm

Answer 17

Combine it into a single fraction.

Answer 18

Ok then? :/

Answer 19

i still dont get it :P

Answer 20

You're suppose to solve it. Putting it into a single fraction then distribute -2x^3 over x-3.

I made an attempt to try to help you. :/
