2,150 estimated would be 2,000. Since she flies there and back multiply 2,000 by 2. Since she flies it twice multiply 4,000 by 2. Estimated: 8,000 miles. To find the exact miles Do the same thing but with 2,150: 2,150 times 2 = 4,300. 4,300 times 2 = 8,600. She flies exactly 8,600 miles per year :)
X=5 if that's what you were asking for
D) Vertices: (1, -1), (-11, -1); Foci: (-15, -1), (5, -1)
M^2 = 49
M^2 = 7^2
M = -7 and M = 7
