D would be the most reasonable because the whole set up adds up to 10 and you only have a chance of drawing all of the colors in a row
A because you subtract 15from 20 and it =5 or 1/4
K is whatever you want it to be
We know that
X²+y²=9 -------> X²+y²=3²
is the equation of a circle with center (0,0) and radius r=3 units
so
<span>the translation of four units to the right and three units down is equals to move the center (0,0)--------> (0+4,0-3)------> (4.-3)
the new center of the circle is (4,-3)
the new equation is
(x-4)</span>²+(y+3)²=3²
see the attached figure
