(x+8)^(2) + (y+9)^(2) = 169
(x+8)^(2) + (y+9)^(2) = 13^2
h = -8
k = -9
r = 13
answer
A. center (-8,-9)
radius = 13
--------------
(x-7)^2 + y^2 = 225
(x-7)^2 + y^2 = 15^2
h = 7
k = 0
r = 15
answer
B. center (7,0)
radius = 15
Answer:
27
Step-by-step explanation:
25,16,21,30
Put the numbers in order from smallest to largest
16,21,25,30
The median is the middle and the median is 25 so the new number must be 25 or larger
The only number on the the list that is 25 or largest is 27
4/5 is NOT a multiple of 1/4 because the denominators are not divisible by each other.
The ratio would look like 63:3.5, if simplified it would look like 18:1
