-6 + 6 = 0 0 + -2x = 12 + 6 -2x = 12 + 6<span>4x+2(x-3)=8x+12  is our main problem right? so...
</span><span>4x + (-3 * 2 + x * 2) = 8x + 12
4x + (-6 + 2x) = 8x + 12
</span><span>So next we do: 
</span><span>-6 + 4x + 2x = 8x + 12
Reorder the terms :)    </span><span>-6 + 6x = 12 + 8x
</span>Now were going to solve for x
<span>-6 + -2x = 12 + 8x + -8x
</span><span>8x + -8x = 0
-6 + -2x = 12 + 0
-6 + -2x = 12
</span>-6 + 6 = 0
0 + -2x = 12 + 6
-2x = 12 + 6=
<span>-2x = 18
so now were just going to divide each side by -2
and so thats going to be like this
-2x = 18</span>
/ -2     /-2
0        -9
so whats left over is x = -9
So your answer is A.

SOS I'm terrible at math.
Tresset [83]
<span>y = -5 cos x is a basic (simple) variation of the basic trig function y = cos x.

The given </span>y = -5 cos x could be re-written as <span>y = -5 cos 1x.
Compare this to the most general form:          y =  a cos bx.

Here we see that the coefficient b equals 1.

There is a rule for finding the period of such a function:  Period = 2pi/b.

Since b = 1 here, the Period here is 2pi/1, or simply 2pi.

Please stop saying "I'm terrible with math."  That does not help you at all.  Say, instead, "With just a little help I could understand this just fine."</span>

What is 3.116372 rounded to the nearest hundred thousandths place?
Neporo4naja [7]
Answer: 3.11637

Explanation: The hundred thousandths place is in the fifth place after the decimal. To avoid remembering this, you can simply note that the first place after the decimal is the tenths. You simply keep progressing as you would in whole numbers.

For example 10 becomes 100 when a zero is added. This zero is always added right beside the first zero and indicates the hundreds place.

Furthermore, the general rule for rounding is if the number after the preferred rounding place is 4 or less, the number remains the same. 5 or more means it goes up by one digit.
