It's so annoying and boring, I'm doing algebra and triginometry for college students.(adsbygoogle = window.adsbygoogle || []).push({});

I feel like I did all this already in high school but it was a coupla years ago and I've forgotten it and this teacher is just so boring, but I try to adjust the best I can. That's why I just needed some help. She doesn't really explain anything and she goes so quickly...

Right now we're on like inequalities and factoring binomials. Atleast they're better than some of the stuff we were doing.

Here's something I didn't know what the hell the professor was talking about if you wanna help me out on it and get me up to date on it:

Actually well these are all the topics I've done so far:

Integral Exponents & Scientific Notation

Functions, Domain, Functional Notation, Vertical Line Test

Graphing Linear Functions, Slope, Equations of Lines, Introduction to Graphing Calculator

Solving Systems of Equations: Graphically and Algebraically

Linear & Compound Inequalities & Absolute Value Equations

Graphing Linear Inequalities(by hand and with a calculator)

I was confused on the solving systems of equations and absolute value equations the most, how do you do them? Here are some examples if anyone wants to help me out:

|4y + 3| = |4y + 5| How would I find the solution set of that?

|4x - 9| = |2x + 1|

|2x/3 - 2| = |x/3 + 3| How would I solve that?

And lastly: Graph each inequality:

y < -1/3x

Graph the solution set of each system of inequalities:

x - y <= 4

y >= 2x - 4

For that one I would change the sign of the first one to an equal sign and draw a solid line through 4 on both axis right? But how would I do the 2nd one?
