The equation of the circle with center at (2,-4) and tangent to the line x = -2 is given by:
(2) (x - 2)² + (y + 4)² = 16
<h3>What is the equation of a circle?</h3>
The equation of a circle of center and radius r is given by:
The circle has center at (2,-4), hence .
The center is tangent to the line x = -2, hence it has a point at x = -2, since |-2 - 2| = 4, r = 4 -> r² = 16.
Hence the equation of the circle is given by:
(2) (x - 2)² + (y + 4)² = 16

So the sum of 17 and a number x means to add them on one side of the equals sign. The other side would be your 20.
17 + x = 20
5% of the kids are in health. I got this from simplifying 3/60 which is 1/20
After that, i set up this equation: 1/20 times x/100
I would then divide 20 and 100 to get 5 and that’s basically what I did
Answer:
4x+10
