Answer:

x^2 + y^2 -4x -6y + 9 = 0

Step-by-step explanation:

To write a circle in standard form, expand the equation of the circle and move all terms to one side.

(x-2)^2 + (y-3)^2 = 4\\x^2 -4x + 4 + y^2 -6y + 9 = 4\\x^2 +y^2 - 4x - 6y + 13 = 4\\x^2 + y^2 -4x -6y + 9 = 0

Can Someone Please Help ASAP! F(x) = -2 (-3+3) +1
lisov135 [29]

Answer:  Your question is written f(x) = -2*(-3+3)+1.  I'll assume you need the answer for just the one value of x (-3)?  If so, f(-3) = 1.

Step-by-step explanation:  

f(x) = -2*(-3+3)+1

f(x) = -2*(0)+1

f(x) = 1

Other values x for the equation f(x) = -2*(x+3)+1:

-2 is -1

1  is -7

3 is -11

If a marble is randomly chosen from a bag that contains exactly 6 purple marbles, 4 blue marbles, and 10 green marbles, what is
irina [24]
6 purple, 4 blue, 10 green

"What is the probability that the marble picked will not be green?"

Well, simply all the purple and blue together :)

6 + 4 = 10

So, 10 marbles are not going to be green.

So, 10 green, 10 non-green.

So, our probability is 10 : 10

Which, simplified, is 1 : 1
