Step-by-step explanation:
8x + x² - 2y + y² - 64 = 0
(x + 4)² + (y - 1)² - 81 = 0
(x + 4)² + (y - 1)² = 81
Hencr the center is (-4,1) and the radius is 9.
The answer is anything that adds up to 7.
Examples: (5 + 2) or (3 + 4)
Answer:
<h3>
2642km</h3>
Step-by-step explanation:
Given the map coordinates o a bird during travel from Vermont at cordinate (63,45) toto Venezuela at map coordinates (67,10). In order to know how far the bird has travelled, we need to find the distance between the two coordinates first using the formula;
D = 
Given x₁ = 63, y₁ = 45, x₂ = 67, y₂ = 10

If each map coordinate represents 75 kilometers, then the birds distance in km will be 75*35.2278 = 2642.087km
Hence the birds distance in km will be 2642km to the nearest kilometers
Answer:
yes, all answers are correct
Step-by-step explanation:
Answer:

Step-by-step explanation:
This is the answer because:
1) 185 equals to
because 18% is equal to 0.18 which is
2)
to it's lowest terms is 
3) It's lowest terms is
because 18/2 is 9 and 100/2 is 50
4)
can't be simplified any further because 9 and 50 don't have any common factors
Hope this helps! :D
