Someone post a real math problem plz

I did... everyone ignores pictures of circles.

Find the angle X between the vectors:
u=5i + 5j
v=-6i + 6j

v=-6i + 6j

wait wtf is this y = mx + b format?
no there are 3 variables what

i and j are vector segments. i is treated like x and j is treated like y, just in a different format.

oh right, just was introduced to that in conceptual physics, but it was explained at 100mph, so i really don't understand it.

You mean resulting directions and forces/speeds? That's what this question leads to.

forget oldcigarettes i'm doing god damn geometry and all i do is write proofs forget.

being freshmang sucks

searched it up, it uses cosine and i haven't really learned that, lol.
it also looks like there's supposed to be a k as well, unless k is a 0.

aaa this math is very mean

oh good, someone is at my level.

Considering most people on these forums range from ages 10-30, I don't think this thread was a very good idea.

Problem:
x

SOLVE FOR X

[Ticonderoga]

x= lR

2x+3Y+z=34
x+y+4z=2
4x+2Y+7z=24

Solve using the Guass-Jordan method matrix.

[Squideey]

x= lR

use numburs dawg

[kevin 51l]

Problem:
x

SOLVE FOR X

I DIDN'T STUDY

speaking of study i actually have a test tomorrow guys what do.

[Ticonderoga]

use numburs dawg

lR = All Real Numbers
