bearing in mind that "a" is the length of the traverse axis, and "c" is the distance from the center to either foci.
we know the center is at (0,0), we know there's a vertex at (-48,0), from the origin to -48, that's 48 units flat, meaning, the hyperbola is a horizontal one running over the x-axis whose a = 48.
we also know there's a focus point at (50,0), that's 50 units from the center, namely c = 50.

I believe the correct answer is zero
Hopefully this helps
Answer:
Step-by-step explanation:
lets rewrite the equations so that the x and y are on one side and the constant on the other.
2y-x=3
-y+x=0
(we can cancel out the x because one is positive and one is negative)
y=3
(now plug the y value into any equation you want to)
-(3)+x=0
x=3
so our values are
x=3,y=3
B because half the time the answers is B
Answer:
5 milliliter per second
55 seconds
Step-by-step explanation:
first question:
275 - 210 = 65 ml
65 ml : 13 seconds = 5 ml per second
second question:
275 ml : 5 ml = 55 seconds
