(B)
Explanation:
4 quarts are in a gallon so one gallon equals 4(1). The one represents the amount of gallons so if there are x gallons it would become 4(x)
Answer:
The center is at ( (-1, -2) and the radius is 5.
Step-by-step explanation:
X^2 + 2X + Y^2 + 4Y = 20
Complete the square on the x and y terms.
(x + 1)^2 -1 + (y + 2)^2 - 4 = 20
(x + 1)^2 + ( y + 2)^2 = 25 Comparing this with the standard form:
(x - h)^2 + (y - k)^2 = r^2
- the center is at ( (-1, -2) and thr radius is 5.
Hello!
To find how far the ship has sailed, we need to use the distance formula. The distance formula is: 
.
Before using the formula, we need to assign the given points to 
and 
. The point (1, 2) can be assigned to and (5, 5) can be assigned to .
With the assigned ordered pairs, we can substitute it into the formula.
Given that each unit represents one mile, then therefore the ship has sailed 5 miles, which is choice A.
