Biology only includes living organisms whereas an environment can include both living entities and the nonliving matter that surrounds them.

Multiply each side by the reciprocal 3/2 (3/2 times 2/3 equals 1 leaving y). 12/1 * 3/2, so y=18

First look up the definiton for a rational number and then go from there. Perhaps your textbook has a glossary or beyond that what is its meaning in a dictionary? Vocab terms can be dicey in any language, and math is no exception.

Out of zero through nine, how many numbers are greater than five?

Negative exponents are better thought of as fractions: 1/m + 1/z / 1/m-1/z. The only difference between the numerator and the denominator is an operation sign. Do you know what to do from here?

What would you do with fractions in arithmetic? Cross multiplication would work here as well. 3 (x+2) = (x-2) x 3x+6= x^2-2x x^2-5x-6= 0 (x-6) (x+1)=0 either x=6 or x=-1 would work

Think of f(x) as being pretty much like y. The domain is what you are allowed to put in for x in order to get some f(x) or y to come out. That is called the range, but, anyway, are there any x values that you can see as being troublesome? Which x's work f...
