First, substitute -2 into each equation where there is an <span>x:
</span>(-2)2 -8<span>
</span>(-2) +6
Then multiply the -2 and the 2 in the first equation and add -2 and 6 in the second:
-4 -8
4
Lastly, subtract -4 and 8:
-12
4
Now you have you answers -12 and 4!
In the given system of equations, the value of x is 7.334 and the value of y is 7.714
<h3>Solving system of linear equations</h3>
From the question, we are to solve the given system of linear equations
The given system of linear equations is
3x + 7y = 76 ------------ (1)
9y + 5y = 108 ------------ (2)
From equation (2), solve for y
9y+ 5y = 108
14y = 108
y = 108/14
y = 7.714
Substitute the value of x into equation (1), to determine the value of x
3x + 7y = 76
3x + 7(7.714) = 76
3x + 53.998 = 76
Subtract 53.998 from both sides of the equation
3x + 53.998 - 53.998 = 76 - 53.998
3x = 22.002
Divide both sides of the equation by 3
3x/3 = 22.002/3
x = 7.334
Therefore,
x = 7.334 and y = 7.714

To convert 1.07 to a fraction, multiply it by 100.
1.07 * 100 = 107
So the percent equivalent of 1.07 is 107%.
Just put 1.07 over 100 to turn it into a fraction.
107/100 would be the fraction equivalent.
Answer:
In the graph of a circle, we can easily draw a straight vertical line passing through its center. This will hit the top and the bottom of the shape. Since this line hits two points, a circle's graph is not a function. We can also observe the equation of a circle.
