The second answer because addition is commutative.
ADDING THE 2 EQUATIONS TO ELIMINATE Y WE HAVE
-2.98x = -8.94
x = 3
Plug x=3 into first equation:-
-0.18(3) + y = -6.54
y = -6.54 +0.54 = -6
answer x= 3 and y= -6.
The conic section that the above equation represents is a CIRCLE.
Use completing the square for y and put the equation in standard form:
<span>x</span>²<span>+ y</span>²<span> - 4y + [(-4)/2]</span>²<span> - 1 = 0 + [(-4)/2]</span>²
<span>x</span>²<span> + y</span>²<span> - 4y + (-2)</span>²<span> - 1 = 0 + (-2)</span>²
<span>x</span>²<span> + y</span>²<span> - 4y + 4 - 1 = 4 </span>
<span>x</span>²<span> + (y - 2)</span>²<span> - 1 = 4 </span>
<span>x</span>²<span> + (y - 2)</span>²<span> = 4 + 1
</span>x² + (y -2)² = 5
The radius of the circle is the square root of 5. Its center is found at (0,2)
