The original price of an article was reduced by 25 percent. During a special sale the new price was decreased by 10 percent.By approximately what percent would the price now have to be increased in or
of the line passing through the point (-2,5) and parallel to the line y=4x+6.
[A] y= 4x+13
[B] y= -4x-13
[C] y= 4x-22
[D] NONE OF THESE.-Definitely A.Let me know if you want an explanation to how
Im really stuck on these problems...
1. x dx + (y - 2x) dy = 0
2. dy/dx = (y - x) / (y + x)
Thanks alot....-1)
x dx + (y - 2x) dy = 0
x dx = - (y - 2x) dy
x dx = (2x - y) dy
x / (2x - y) = dy/dx
Do YOU feel its bad?
If not, dont worry what other people think.
If you do, work to get yourself out of that position.
Just because you are not up to the same level as someone else doesnt mean you
4x^3 = 100x
There should be three answers, I believe.-you should subtract 100x from both sides to get:
4x^3-100x. factor out an x
x(4x^2-100). this tell us x is one zero. now lets find where 4x^2-100
(x-1)² -9(y-1)²-9(y-1)^2 = (3y-3)^2
Now use the following formula for factorisation
(a^2-b^2)=(a+b)(a-b)
(x-1)^2 - (3y-3)^2
= (x-1+3y-3)(x-1-3y+3)
= (x+3y-4)(x-3y+2)-(x-1)² -9(y-1)² =
((x - 1) + 3(y -
I cant get the right answers for these last two problem of my calc webwork.Answers for one or both will be much appreciated.

A sink can be filled from the faucet in 5 minutes. It takes only 3 minutes to empty the sink when the drain is open. If the sink is full and both the faucet and the drain are open, how long will it ta
Im having trouble with this question if you guys know the answer could u please give the formula that you used and how you got it THANKS!
- Each number from 1 to 60 is written on one of 60 index card
17.5 = (x - 1050)/210
the methods Ive tried dont seem to work.-17.5 X 210 = x - 1050
3675 = x - 1050
3675 + 1050 = x
x = 4725-.: 17.5 x 210 = (x-1050)/210 x 210
.: 3675 = (x-1050)
.: 3675 + 1050 = x
The first question says to solve for t using logs:
7 x 36t = 5 x 2^t
The second question says to put the function in the form P =Poe^kt:
P = 5.23(0.2)^t
How do you figure these problems out.?Thanks
solve for y b and a are constants x and y are variables
pls help I did alot of steps and got down to the quadratic formula-ax + y = b (1)
ax² + y² = c (2)
from 1
y = b - ax
substitute into (2)
ax²
