Answer:
The image is blurry for me
Step-by-step explanation:
1.5 = 1 1/2 = 3/2
When there is a negative exponent, you find the reciprocal of the base, so therefore: 3/2 ^ -2 = 2/3 ^ 2
Then you square the numerator, then square the denominator: 2^2/3^2 = 4/9
We need to convert the equation of the circle to standard form only then we can find the radius and the center of the circle.

From this equation we can write:
Center of the circle is (-1,1) and the radius of the circle is 4.
