**Math**

The domain is what x values you can successfully input.

**biology**

Mass includes both protons and neutrons.

**math**

-3-5/0-0. The numerator is not what is important. The denominator forces division by zero which is undefined. Some people say that this is no slope, but undefined makes more sense to me. It has a slope, but you just can not define it because it is a vertical line stretching ...

**geometry**

This is not geometry.

**Graphing**

It is a parabola U. See what happens with the y's when you use 0, +1, and -1 for the x's.

**Biology**

Eggs are much larger than sperm.

**Algebra**

Perpendicular slopes are negative reciprocals of each other (the product of one times the other is -1). In y=mx+b m is the slope and b is the y intercept. To find intercepts, just find (0,?) (?,0) Parallel lines have the same slope. Horizontal lines have a slope of zero, ...

**Algebra 2**

Subtract for 2x * sqrt of 3=2 Divide for x * sqrt of 3/2=1 What to do from here, I do not know. . .

**Algebra 2**

Is there a way to do this?!

**math**

Distribute that negative 1 through the parentheses and that gets you x+3=-2x-2 Then, add 2x to both sides 3x+3=-2 Finally, subtract 3 from each of the two sides. 3x=-5 Divide through by 3 and what is X?

**intermediate algebra**

3 (-2)^8 / 4 What is negative 2 times itself eight times? Should the sign be postive or negative with an even number for an exponent? Look at your rules for raising to a power, and then try again.

**IDK**

I have never used a money order before. From where can one obtain them? How do they work?
