50% is exactly half, so to find half of something you just divide it by 2= 7.5
Or you could multiply it
15 x 0.50=7.5
Answer:
The equation of a circle:
Step-by-step explanation:
The equation of a circle:
(where the center is known as and the radius, known as ).
-Since you already have the center and the radius, use them for the equation of a circle:
Center:
Radius:
After you have the equation of a circle, simplify the radius by the exponent :
So, you have found the equation of a circle.

U can plug in those answers like 15 for x or -21 into y try that or else get x on one side by subtracting 5x and the equation would be 2y=-5x+4 and solve that way
