There is a difference. Please do not just copy a question from a texbook or assignment. I WILL REJECT IT. I will only accept questions, if in addition to the statement of the problem, you describe in detail what you have tried so far in order to solve it, and what exactly is the problem you are encountering. In other words where/why are you stuck? I can answer questions at the level of the first couple of undergraduate years (in science and engineering) or below. You can ask me about algebra, trigonometry, basic probability and statistics, calculus (vector calculus), differential equations and Fourier analysis. I will not answer advanced (at the graduate level) math questions. Questions in Spanish are also welcome.

2009-11-20 variables on both sides:

The parenthises mean to multiply what is on the outside by each element in the indside. Thus, our equation becomes 4y + 4 = 7y - 14. Subtracting -7y from both sides to put the y's on the left gives

2009-11-17 Algebre - Parabolas:

The easiest way to answer your questions is to plot the parabola. For y = 0, x = -3 Put in y = +/- 1, +/- 2, +/- 3. calculate the corresponding values for x and plot x,y for each point. Do that and

2009-11-17 Variation and problem solving:

It is said that x = Ay/√z. Putting in x=5/2, y=2, and z=16 give us 5/2 = 2A*(1/√16) = 2A/4 = A/2. Since 5/2 = A/2, it cam be computed that 5=A. The equation is x = 5y/√z, so put
