Step-by-step explanation:

x² + y² − 8x + 10y − 8 = 0

Rearrange:

x² − 8x + y² + 10y = 8

To complete the square, take half of the x and y coefficients, square it, then add the result to both sides.

(-8/2)² = 16

(10/2)² = 25

x² − 8x + 16 + y² + 10y + 25 = 8 + 16 + 25

x² − 8x + 16 + y² + 10y + 25 = 49

Factor the squares:

(x − 4)² + (y + 5)² = 49

The center is (4, -5) and the radius is 7.

Hair color is an inherited trait. In Marci's family, her mother has brown hair. Her father has blonde hair. The family has 6 chi

Answer:

the number of children has red or brown hair is $\frac{2}{3}$ .

Step-by-step explanation:

We have been given that in Marci's family there are total 6 children.

Out of 6 children

Number of children have blonde hair = $\frac{1}{3}$

Number of children have red hair = $\frac{1}{6}$

Number of children have brown hair = $\frac{1}{2}$

Since, we have to find the fraction of children has red or brown hair= $\frac{1}{6}+\frac{1}{2}=\frac{4}{6}=\frac{2}{3}$

Hence, the number of children has red or brown hair is $\frac{2}{3}$
