Answer:
a) 5 and 10
b) 15
c) The center-to-center distance is the sum of the radii, so the circles must be tangent.
Step-by-step explanation:
a) Each equation is in standard form:
(x -h)^2 + (y -k)^2 = r^2
so the first circle has radius √25 = 5, and the second circle has radius √100 = 10. The radii of the circles are 5 and 10.
__
b) The center-to-center distance can be found from the distance formula:
d = √((x2-x1)^2 +(y2-y1)^2) = √((9-0)^2 +(12-0)^2) = √(81 +144)
d = √225 = 15
The distance between centers if 15 units.
__
c) The circles must be tangent because their center-to-center distance is the same as the sum of their radii.
5 + 10 = 15
This is a geometric sequence and the common ratio is 0.5.
So, the next term will be 2.75.

Answer: y= -2x + 24
Step-by-step explanation
2x - 4y = 24
subtract 2x from both sides
divide 4y by 4y to get y by itself
then you get y= -2x + 24
<span>(x+3)^2 = x^2 + 69
x^2 + 6x + 9 = x^2 + 69
x^2 + 6x + 9 - x^2 = x^2 + 69 - x^2
6x + 9 = 69</span>
