<h3><u>The value of y is -7.</u></h3><h3><u>The value of x is 8.</u></h3>
First we need to rearrange these equations so they line up properly.
6x - 2y = 62
-x + 2y = -22
Add equations together.
5x = 40
Divide both sides by 5.
x = 8
We can plug this value in to find the value of y.
6(8) - 2y = 62
48 - 2y = 62
Subtract 48 from both sides.
-2y = 14
Divide both sides by -2.
y = -7
Area of 3400 decreases by 7.25%.
Rewrite 7.25% as a decimal.
This leads to 0.0725.
So, (3400)(0.0725) = 246.5.
Now (246.5)(13 years) = 3,276.
The area after 13 years will be
3,276 km^2.
<u>Answer:</u>
Third graph
<u>Step-by-step explanation:</u>
We are determine whether which of the given graphs is that of the linear inequality 
.
We know that, on the graph the greater than sign (
) represents the shaded part above the line and less than sign (
) represents the shaded region below the line.
While the signs 
or 
is denoted by a solid line on the graph.
Therefore, the third graph represents the given inequality.
