When water fills a submarine’s flotation tanks, what happens to the submarine?

the buoyant force is reduced.

its overall density decreases.

its overall density increases.

its overall density stays the same

It over all density increases and it begins to sink.

this isn't the answer but they're the graphs

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14
