How do you factor the (x-2) opt, I do not understand the steps to do this?

I do not want the limit i just need the derivative so I can set it equal to 15

Well can you make it easier to understand how you got it?

I mean how you got it? Your explanation is very confusing

how do I do this?

I understand what you are saying but how do you do the algebra foe 6=2x+4/x I seem to have forgotten my algebra.

No i need help understanding the algebra behind solving 2x+4/x=6

okay a. 3.1 b. 6.0 c. 42 d. 6.0 x 10^23 e. 18 f. 10. g. 4.5 x 10^2 h. 1.2

these are my answers could someone check them for me

so this is right, each number can only have two digits for f. should it be 10 or 10.

what if I change the 1-x to a y? how do you solve for 2 variables?

You're right, it is 2x^2.

668= 26.7(2.42)(X-32.5) ?

ohh, i didn't realize! thankyou :)

The Awakening, by Kate Choplin, sorry

How do you figure out if acceleration occurred. What would the equations look like?

.78 to nearest hundred

the y0 should actually be y with a little 0 at the bottom right corner and as i said from the equation it is the amount of initial dose. Plus the initial dose is 200mg not 20 sorry. so how long would it take to get from 200mg to 50mg?

because the answer has got to be a real number which is not a negative number

how do you get 1/2 as a solution?

So technically there would be no solution right?

the quadratic formula is -b+-radical b^2-4ac/a

SO HOW DO YOU GET 1/2 FORM THAT?

PV=nRT (1)(x)= (.250)(0.0821)(523) 1x= 10.73

How did you get the answer .117 ?

thank u so much Ms.jordan
