Answer:
y = cos x + 2
Step-by-step explanation:
The graph of y = cos x begins at y=1 when x=0, that is, at (0, 1). If we translate the entire graph of y = cos x upward by 2 units, we get the graph shown. The correct answer is b: y = cos x + 2.

I don really understand as well but i will give what i say it would be.
I had to round it to the nearest thousand which would be 6,000, from there I divided it in half twice to that would be 4,000 then 2,000 so I would go for C.
Hope this helped!
<span><span>x-4x+12=6
-3x+12=6
-3x+12-12=6-12
-3x=-6
-3x/-3=-6/-3
x=2
Plug (2) in for x in L2 and solve for y:
y=2(2)-6
y=4-6
y=-2
The solution (x,y)=(2,-2)
Check in both equations by substituting (x,y)=(2,-2) and see if it equals out:
L1) (2)-2(-2)=6
2+4=6
6=6 L1 checks out.
L2) (-2)=2(2)-6
-2=4-6
-2=-2 L2 checks out also, so we can say with confidence that the solution is right.
