Answer:
x=1 y=-2
Step-by-step explanation:
2x-4y=10
3x+4y=-5
5x=5
x=1
plug in x
3(1)+4y=-5
4y=-8
y=-2
Answer: 0.884736
Step-by-step explanation:
Given: The proportion of all air travel departs on time: p= 0.96
Total flights : n= 3
Let x be the number of flights on time.
As there are two cases either flight on time or not, so it is a binomial case.
Binomial distribution formula:
The probability that all of them depart on time =
The probability that all of them depart on time = 0.884736
I struggle with proofs too! They're the worst.

l is parallel to n because of the parallel lines theorum,.
∠3≅∠4 becasue converse of alt. interior angles
∠1≅∠2 because converse of alt. interior angles
not sure about the last one but i tink its m ║ n
