if you isolate y in the top equation to get y=5x+6 then you can substiture y for 5x+6 in the bottom equation because thats what y equals
as of now you have -3x+6(5x+6)=-12 but if you use the distrubite property you would get -3x+30x+36=-12
then if you subtract 36 from both sides you would get -3x+30x=-48 then combine like terms to get 27x=-48 then divide both sides by 27 to get 
or x≈1.8
Answer:
-42
Step-by-step explanation:
The objective is to find the line integral of 
around the perimeter of the rectangle with corners (4,0), (4,3), (−3,3), (−3,0), traversed in that order.
We will use <em>the Green's Theorem </em>to evaluate this integral. The rectangle is presented below.
We have that
Therefore,
Let's calculate the needed partial derivatives.
Thus,
Now, by the Green's theorem, we have

<h3>How to solve for the values</h3>
For the first percentage
20 / 100 = x/20
= 20 * 20 = 100x
400 = 100x
divide through by 100
x = 400/100
x = 4
For the second percentage
30/100 = x/20
600 = 100x
x = 600/100
x = 6
For the last
50/100 = x/20
1000 = 100x
x = 10
The proof is that 6 + 4 + 10 still gives us 20

Step-by-step explanation:
I used a calculator on this one.
Answer:
14
Step-by-step explanation:
Next time, please share the possible answer choices.
The absolute value of any quantity, whether it be a + or - quantity, is zero or positive.
Thus, |-14| = the absolute value of -14 = +14
