Its about finding the equation of a circle from its general form equation:
x^2 + y^2 + 8x - 4y - 61 = 0
x^2 + 8x + 16 + y^2 - 4y + 4 = 61 + 16 + 4
(x + 4)^2 + (y - 2)^2 = 81
therefore the center is C(-4, 2), and the radius is 9

Write the decimal as a fraction or a mixed number. Write your answer in simplest form. 0.2

Answer:

$\frac{1}{5}$

Step-by-step explanation:

$0.2 \times \frac{10}{10} = \frac{2}{10} = \frac{1}{5}$

This number can't be written as a mixed number since it is proper fraction.

It's numerator is less than it's denominator.

Hope this helps ;) ❤❤❤
