Which of the following circles have their centers in the second quadrant? check all that apply.
a. (x - 5)2 + (y + 5)2 = 9
b. (x + 12)2 + (y - 9)2 = 19
c. (x + 3)2 + (y - 2)2 = 8
d. (x - 2)2 + (y + 7)2 = 64

B and C

Explanation:

Coordinates of A: (5,-5), which is in the 4th quadrant.

Coordinates of B: (-12,9), which is in the 2nd quadrant.

Coordinates of C: (-3,2), which is in the 2nd quadrant.

Coordinates of D: (2,-7), which is  in the 4th quadrant.

step-by-step explanation:

idk the answer i want to say 10 but then it would be equal so try 9 but then yeah so yeah we love edgen

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
