Hi there! :)
Answer:
<u><em>*THE ANSWER MUST HAVE A NEGATIVE SIGN!*</em></u>
Step-by-step explanation:
First, you subtract by 8 from both sides of an equation.
5x+8-8=9x+12-8
Subtract.
12-8=4
5x=9x+4
Then, you subtract by 9x from both sides of an equation.
5x-9x=9x+4-9x
Simplify by equation.
-4x=-4
Divide by -4 from both sides of an equation.
-4x/-4=-4/-4
Divide by the numbers from left/right.
-4/-4=-1
, <em>is the FINAL/CORRECT ANSWER! :)</em>

3+5+7 = 15 total marbles
3 are red
so she has a 3/15 reduces to 1/5 probability of picking a red one
Y = cos(x)
sqrt(3)/2 = cos(30º)
dy = -sin(x)*dx
dy = -sin(30º)*(pi/180) = (1/2)*(pi/180)
y + dy = cos(x) - sin(x)dx
y + dy = sqrt(3)/2 - (1/2)*(pi/180) = 0.8573

(-8, -5)
To form a rectangle, all the lines must be perpendicular and parallel. If you draw out the points on a coordinate plane then you can find the answer pretty easily.
Also, this one is easy because all the lines are vertical or horizontal, and when that is the case then you can just see which number in the set hasn't appeared twice (1 appeared twice as an <em>x</em> value, 0 appeared twice as a <em>y </em>value, but -8 has only appeared once as an <em>x</em> and -5 has only appeared once as a <em>y </em>value)
