i'm freshening up my mind with algebra 1 stuff that i don't remember exactly how to do, so that i can be ready for algebra 2...

how do i graph something like...

"graph the following"

1. y=3/5X +5


2. y=X2 -2X -2

(X2 means X squared)

thanks a bunch

Maybe it's just a big piece of ice, and it doesn't belong to anyone because no on wants it?

We have our keyboards' keys only to create new URLs; if there is a limit on the number of signs that can be put in the address line, then there should be a limited number of URLs that can be created. Is there a limit though? Or can address lines go on forever? In that case, I suppose, the number of URLs that can be created would be virtually endless?

I've just read a post from a hardcore Christian nut on the religion and spirituality forum. He claims that there are websites describing dinosaur and human footprints both on the same level ie layed down and fossilised at the same time! Has anyone seen this website and can they please direct me to it?

I firmly believe this is really bad and misleading science.
I'm not religious and I think this is total B.S. but I'd like to read about these "Facts" and maybe see some sort of image.

and A is equal to B and B = B miles per gallon@ 1,333,34 lbs What is the value of B ? Or in other words since I probably didn't state that right. If an 18wheeler gets 6 MPG weighing 80,000lbs what would a compact car weighing 1,333.34lbs get for MPG if it were pound for pound equal to the truck?

can someone help me answer this solubility question?

The solubility of ammonium bromide in water at 20 °C is
75.5g/100g of water. At 50 °C it is 99.2g/100g.
a. Calculate the mass of ammonium bromide that will
dissolve in 65.0g of water at 20 °C.
b. Calculate the mass of water required to dissolve
50.0 g of ammonium bromide at 50 °C
c. Calculate the mass of ammonium bromide that
would not remain in solution if a solution made up of
29.0g ammonium bromide in 35.0 g water at 50 °C is
cooled to 20 °C.

also..is there a site that covers sample chemistry problems with provided answers?

I'm majoring in biological sciences and might go into biotechnology, genetics, or cell biology. However, my I'm no mathematician. I know that I'm required to take two years of calculuds at the college I'm attending, and I have no problem with that. But do chemist use a lot of math in the field, besides algebra--which I'm pretty good at?

bad mutations tend to hide in a population, so they build up over time, increasing the chances that a new organism won't be "fit" (when the mutations can't hide behind the original gene. The probability of this is called genetic load)
So, does mutation-selection, a.k.a Neodarwinism, come up with fitter creatures to replace the old ones? If so, how? If not, why do schools say it does? (It sounds like the evolution the schools teach us.)

By symmetric arrangement, what I mean is that when the points are viewed in x-y or x-z or y-z planes, they look the same in the 3 planes.

A boat of 45kg and length 3m is floating in a still frictionless water. A dog of 15kg walks from the bow to the stern. Find the distance through which the boat gets displaced.



The answer would be 0.75m .....I just can't find out how.
