Mathematics

Answer:

C(5, -3)

Step-by-step explanation:

Given the equation of circle;

x² + y² - 10x + 6y - 2 = 0

The general equation for a circle is given by the formula;

x² + y² + 2gx + 2fy + c = 0

Where the center is C(-g, -f)

To find the center, we would compare the two equations;

For the value of g.

2gx = -10x

2g = -10

g = -10/2

g = -5

To find the value of f.

2fy = 6y

2f = 6

f = 6/2

f = 3

Therefore, the center C(-g, -f) = (-(-5), -(3))

C(-g, -f) = C(5, -3).

The number of boys in a school is 120% the number of girls at the school. Find the number
KiRa [710]

Answer:

66 girls

Step-by-step explanation:

Givens:

●120% boys of girls

▪︎1.2 × g

☆when g is the number of girls

●80 boys

▪︎meaning you can set up a proportion

Solving:

g × 1.2 = 80

g=80/1.2

g=66.66

So, since you can't go over percent, the answer is 66.

Checking:

g × 1.2 = 80

66 × 1.2 = 80

80=80✅
