I can proceed. But I don't understand how .6x and .2y became 3 and 1.

I have a word problem that I am struggling with. I have been using matrices in this chapter, but I don't understand how it applies or where to start in order to solve this equation. Here is the word problem: One hundred liters of a 50% solution is obtained by mixing a 60% solution with a 20%...

There cannot be a negative number under the square root and a fraction cannot have zero as a denominator. Knowing that, I still cannot figure out what steps to take to figure the problem out.

How do you find the Domain of \sqrt{(x^2 + 4)/(x^2 - 4)} ?

How would one find the symmetry of the function x^3-3=g(x) ? Or any other symmetry.

5/(x-1) - (2x)/(x+1) - 1 < 0 How does one solve this inequality?

Yes, thank you.

(3x - 5)/(x - 5) > 4 How does one complete this problem?
