I was in physics today and I realized something astonishing, and slightly disturbing:
Δx = VI Δt + ½a Δt2

Is easier for me to figure out than

|4a + 5| > 10

Is this good?
I don't EVER want to see another loving velocity equation on here.
Screwed me up during a test, and it gets worse when you've got Vi for one variable, and acceleration for another, but don't have the other stuff for both of them.

black holes are lovey
i was gonna say this

everything in space is lovey

Theoretically, if you know the value of a, it's an easy problem. Let's say a=(-6).

|4x(-6) + 5| > 10?
Absolute value brackets act as parentheses. (no stuff)
|-24 + 5| = -19

-19 =/= 10

problem solved

Science and math is for loser nerds. I don't need any of that stuff in my life. All I care about is getting paid and getting laid.

Both of which are generally required for the former, unless you're looking into becoming an actor, research-star, or other bullstuff career path.

Yes, science is awesome.

Absolute value brackets do not act as parentheses.
|4x + 5| > 10
This is solved in two cases:
Case 1:
4x + 5 > 10

Case 2:
4x + 5 < -10

The answers to both of these equations are needed for the correct final answer.
Case 1:
4x + 5 > 10
Subtract 5 from both sides.
4x > 5
x > 1.25

Case 2:
4x + 5 < -10
Once again, subtract five from both sides.
4x < -15
x < -3.75

So the answer set is "x > 1.25 or x < -3.75".

Graphing this on a number line is my big problem. I have some understanding of how it works but in practice, I just fail miserably.

Right.

Does oxidation apply to non-oxygen stuff (stupid question)?

So, as an example (transition metals all have 2 valence electrons, or e- for quickness)

Fe + O2 (standard rust) -> FeO + O
Sulfur, theoretically, would have the same effect
Fe + S -> FeS, likely causing decay of the iron in question

Can somebody explain to me why the area around the sun is hotter than the surface of the sun itself, which basically says "forget you and your family" to the second law of thermodynamics?
