<span>If we add these two equations together, we can quickly follow the system via the elimination method as the y-terms cancel out.
Doing so results in 6x= -30, so x = -5. Plug this in and solve for y.
2*(-5) + 3y = -7, -10 + 3y = -7, 3y = 3, y = 1.
The solution is therefore (-5,1).</span>
Factoring completely you get: 3(3x-1)(2x+3)
When using simulation models for random sampling, we can develop the margin of error by multiplying the critical value by the standard error.
<h3>What is the margin or error?</h3>
This is a measure of the error that we get when we use a random sampling model.
It can be found by the formula:
= Critical value x Standard error
If using a z-test, the critical value would be z and the standard error would be (σ / √n). The margin or error would therefore be:
= z (σ / √n)

96.493 rounded to the nearest tenth is 96.5.
That is because 0.493 is closer to 0.5 than it is to 0.4.
Answer:
y = 64
Step-by-step explanation:
The angles are supplementary, that is sum to 180° , thus
2(x + 6) + y = 180 ← substitute x = 52
2(52 + 6) + y = 180
2(58) + y = 180
116 + y = 180 ( subtract 116 from both sides )
y = 64
