Answer:tickets in Germany cost $8.93
tickets in France cost $8.85
Step-by-step explanation:
Let x represent the cost of a movie ticket in Germany.
Let y represent the cost of a movie ticket in France.
Four movie tickets in Germany plus 3 movie tickets in France cost &62.27. This means that
4x + 3y = 62.27 - - - - - - - - 1
three tickets in Germany plus 4 tickets in France cost $62.19
This means that
3x + 4y = 62.19 - - - - - - - - -2
Multiplying equation 1 by 3 and equation 2 by 4. It becomes
12x + 9y = 186.81
12x + 16y = 248.76
Subtracting,
- 7y = - 61.95
y = - 61.95/7
y = 8.85
Substituting y = 8.85 into equation 1, it becomes
4x + 3×8.85 = 62.27
4x + 26.55 = 62.27
4x = 62.27 - 26.55
4x = 35.72
x = 35.72/4 = 8.93

Answer:
Given the focus (h,k) and the directrix y=mx+b, the equation for a parabola is (y - mx - b)^2 / (m^2 +1) = (x - h)^2 + (y - k)^2.
Step-by-step explanation:
Answer: 1. 7:10
