Answer:
y=-2/3x-4
Step-by-step explanation:
Answer:divide the opposite sides, by the length of the hypotenuse. To get the cosine, divide the length of the adjacent side,by the length of the hypotenuse.

Option B:
is the correct answer.
Explanation:
Option A: 
Simplifying, we get,

Since, the value of
is greater than
, the comparison
is false.
Hence, Option A is not the correct answer.
Option B: 
Simplifying, we get,

Since, the value of
is greater than
, the comparison
is true.
Hence, Option B is the correct answer.
Option C: 
Simplifying, we get,

Since, the value of
is greater than
, the comparison
is false.
Hence, Option C is not the correct answer.
Option D: 
Simplifying, we get,

Since, the value of
is greater than
, the comparison
is false.
Hence, Option D is not the correct answer.
Answer:
Well elimination is basically multiplying a number to make it possible for it to cancel out
We can multiply the first equation by 2
2(x+2y=-1)
This would be
2x+4y=-2
Its still the same thing but just with non simplified numbers
We can now do any method really to solve
I will just do the subtraction method
2x+4y=-2
-2x+y=4
Solve
2x-2x=0
4y-y= 3y
-2-4= -6
3y= -6
Now solve
y=-2
To find x subsitute in “y” and find ”x”.
x+2*-2=-1
x-4=-1
x=3
y= -2
x= 3
