I also do not get these inverses questions y = 5(x-3)^3 x = 5(y-33)^3 I divided 5 on both sides and got 1/5x = (y-3)^3 Then do I cube root the 1/5x or something to get rid of of the cubed on (y-3)? Also y = x-2/5x-3

thanks Steve but i think im still messing up. i got 30 = x+30 and if i subtract 30 from each side then i only left with x that be no solution. i think i not doing something right.

thanks very much steve i got it :)

thank you so much damon :)

sorry yes you are right but don't all 2x-1's cancel?

13 years ago

i think it supposed to be this (4x+3)(-2) = (6x+2)

13 years ago

thank you but in back of book it say no solution so i very confused.

13 years ago

thank you so much i not notice that either. thanks :)

thanks jordan and reiny :) but reiny i not understand the whole absolute value thing becuase for -|-sqrt81| you get -9 and that not positive.

13 years ago

okay so everything in || will always be positive? and can u please explain how did u get rid of the two extra lines here ||3-|9||.

13 years ago

you're welcome glad i could be a help :)

13 years ago

okay those bracket lines really confusing. how you get |5-32| because that negative sign be separated from f and -32. sorry i just real confused right now

13 years ago

i not meant f i mean 5.

np :)

13 years ago

okay wait i think i sort of get it now. and absolute value mean how far you are from 0 ?

13 years ago

thanks very much steve :)

13 years ago

i get it! thanks reiny :D

13 years ago

thank you damon :)

13 years ago

thank you for the 3x-1 = -5 it says in back of book that there are no roots of the equation |3x-1| = -5 and i not see how that be possible.

13 years ago

ok can u explain to me again that i still not get it.

13 years ago

thank you guys so much if you have time to spare can i post more questions? i not know when you guys go to sleep.

13 years ago

btw this is actually pre-calculus publisher is absolute value publications

13 years ago

it actually say to use quadratic formula so i subtract 4 from both sides to get an equation by itself so i plug it in?

13 years ago

will you guys be here early in the morning?

13 years ago

i forgot put the other one -- -(x+4) = -(x-2) -x+4 = -x+2 4 = 2 no solution

13 years ago

i think that be wrong the real answer have to be -4/5 and 8 i just not know how to get thats.

13 years ago

thank you damon i have lots more questions i posted that i not understand they i think be real down below other peoples questions.

13 years ago

sorry i missing part of question whole question be |x^2-2x-6| = 4. and answer have to be 1+-sqrt3, 1+-sqrt11 i just not get how to get this.

13 years ago

its alright and thanks :)

13 years ago

thanks:)

@ Anonymous if you not busy can u please look at my other questions below?

13 years ago

thank you very much the site be very very helpful i try to find site like that yesterday and i not find thanks very much.

13 years ago

o never mind i get it. i see i not supposed to multiply by 100 i supposed to divide.

13 years ago

Milli means 10 cause there be 10 millimeters in 1 cm. only thing i get wrong be that i times 0.0023mm by 10, i supposed to divide to give me cm. then to get cm into meters i divide by 100 cause there be 100 cm in 1 m. then i get 2.3*10^5.

13 years ago

ok sorry i actually just found that i word it wrong it was not supposed to be 0.0023, it supposed to be 0.023. thanks for helping, i appreciate it :)

The question in my book only has brackets around (x+5/2)

13 years ago

I still don't understand the whole process

13 years ago

Thanks so much, does the amount of acid also matter? like 2.0M or 6.0M? and if its powdered that also increases the reaction rate right?

13 years ago

Alright but since heat is released wouldn't it be negative? the H notation?

13 years ago

sorry that was the wrong question I meant the degrees of these one were both the same: y = x^2+5x-6/x-3x^2+9 the leading coefficient is 1, so the vertical asymptote would be one?

13 years ago

for the last two you did how do you know the x is becoming large like that whole infinity thing?

how do i log both sides? divide by 2000 on both sides?

12 years ago

Thanks very much Reiny :)

12 years ago

thanks soo much Reiny :) You are such a great math helper on here! :D

12 years ago

so you added 10 and 2 to get 12, and amplitude is the middle of max and min? how did you get the axis 4 units? a period is always twice of something? the phase shift is sort of confusing me, because isnt that just between the x values? 2, and 5? is there...

12 years ago

Oh that makes sense, thank you :)

12 years ago

Aww thanks soo much buddy :)

How do you know which ka to use? There is one on the base side of the chart, and one of the acid side of the chart. For the one of the acid side of the chart, the Ka is 2.2*10^-13 And for the one on the base side of the chart, it is 6.2*10^-8.

12 years ago

Thanks so much :) So if we were to find the Ka, then we would use the ka on the acid side of the chart?

Thanks soo much to both of you :)
