11.4 should be the answer
if you mean tens then it is 10

The answer is B
Step-by-step explanation:
Im on Edg right now and I got the answer
Answer:
(2, -3) and r = 3.
Step-by-step explanation:
you can also plug this equation in desmos but I guess it's good to know how to do it also:
The equation of a circle is (x-h)^2 + (y-k)^2 = r^2
Now in order to make a perfect square on both sides, we need to do this:
First add 9 to both sides:
x^2 + 6x + 9 + y^2 -4y +4 = 9.
I purposely shifted it to show the perfect square created when you add 9 to both sides. Factor:
(x+3)^2 + y^2 - 4y + 4 = 9.
now the second bolded part is allso a perfect square. Factor:
(x+3)^2 + (y-2)^2 = 9
Based on the equation of a circle, the center must be at (2, -3) and the radius is the square root of 9 which is 3.

Answer:
m= 4, b = 3 matches with y = 4x +3
m=5, b = -2 matches with y = 5x - 2
m = 3, b = 4 matches with y = 3x + 4
m = -2, b=5 matches with y = -2x + 5
Step-by-step explanation:
Slope-intercept form is <em>y = mx + b</em><em> </em>in which m = slope and b = y-intercept
