Answer:
1 circle
Step-by-step explanation:
Given two circles (red circles on the diagram).
There are two tangent circles to both of the given circles (blue circles on the diagram), and only one of them is passing through the point (0,5).
Let's check it.
The equations of the tangent circles are
![x^2+y^2=9\ [\text{Smaller tangent circle}]\\ \\x^2+y^2=25\ [\text{Larger tangent circle}]](https://tex.z-dn.net/?f=x%5E2%2By%5E2%3D9%5C%20%5B%5Ctext%7BSmaller%20tangent%20circle%7D%5D%5C%5C%20%5C%5Cx%5E2%2By%5E2%3D25%5C%20%5B%5Ctext%7BLarger%20tangent%20circle%7D%5D)
Check whether point (0,5) lies on the smaller circle:

No
Check whether point (0,5) lies on the larger circle:

Yes
<u>Answer: </u>1 circle
Answer:
14
Step-by-step explanation:
164 = 8x + 52
Subtract 52 from both sides
112 = 8x
Divide both sides by 8
14 = x
Answer:
25.100
Step-by-step explanation:
The thousandth place is the third digit to the right of the decimal point - tenths is the first, hundredths is the second, thousandths is the third. Since six rounds up and both nines round up, one must round up all of the way from the fourth decimal place to the tenth decimal place.
To find the pre image you need to back track on the image. To get to the image you used (x-6,y+8). Now you need to use the exact opposite to get back to the pre image. For this you would change the signs to look like (x+6,y-8). Now we just apply this to (-4,1).
(-4+6,1-8)
(2,-7) should be the pre image point.
