Your answer is option H.

First find the equation of the circle. 

The formula of a circle is (x - h)² + (y - k)² = radius² where (h, k) is the center. So we plug in the given information. Diameter is 10, so radius is 5. 

Your equation becomes:

(x + 2)² + (y + 2)² = 25

Now you plug in the ordered pairs. It can' be option F because that's the center. Next one I plugged in was option H, (- 6, - 5).

(- 6 + 2)² + (- 5 + 2)² = 25
( - 4)² + (- 3)² = 25
16 + 9 = 25
25 = 25

Because plugging in (- 6, - 5) gives you a true statement, it lies on Circle O.

Solve the following problem using linear systems: You have a bottle of a 2% solution of iodine and a bottle of a 66% solution of
vagabundo [1.1K]

The quantity of liters of the 2% and 66% solutions should you mix together is 4.75 and 11.25 liters.

let

  • x = liters of 2% solution
  • y = liters of 66% solution

x + y = 16

0.02x + 0.66y = 0.47 × 16

from (1)

x = 16 - y

Substitute into (2)

0.02x + 0.66y = 0.47 × 16

0.02(16 - y) + 0.66y = 7.52

0.32 - 0.02y + 0.66y = 7.52

- 0.02y + 0.66y = 7.52 - 0.32

0.64y = 7.20

y = 7.20/0.64

y = 11.25 liters

Substitute y = 11.25 liters into (1)

x + y = 16

x + 11.25 = 16

x = 16 - 11.25

x = 4.75 liters
