Find the greatest common factor
in this case it would be 8, so she'd be able to make 8 packets maximum
Answer:
The answer to the question is C
Answer:
(x - 3)^2 + (y - 5)^2 = (√89)^2
Step-by-step explanation:
Well if you estimate, you can see that the circle touches one point at (-5, 0) and the center is at about (3, 5).
The standard equation for the circle is (x - h)^2 + (y - k)^2 = r^2 where (h, k) is the center.
So, you can start by plugging in the center. (x - 3)^2 + (y - 5)^2 = r^2
Now, all you have to do is find the radius.
You can do this by connecting the point (-5, 0) to the center.
You will have to use the distance formula:
√(-5 - 3)^2 + (0 - 5)^2 = √64 + 25 = √89
The final equation will be (x - 3)^2 + (y - 5)^2 = (√89)^2
This is the general idea, but my answer may not be correct, so check my steps.
y - 3 = x
x^2 - 6x + 13 = y
--
y = x + 3
x^2 - 6x + 13 = x + 3
x^2 - 7x + 10 = 0
x^2 - 5x - 2x + 10 = 0
x (x - 5) - 2 (x - 5) = 0
(x - 2) (x - 5) = 0
x = 2, or x = 5
The answers choices only have one solution where x = 2 or x = 5, so the answer is (2, 5).
Yes I can what is it that your are having trouble with?
