2. |2+(-4)| = 2 |2| + |(-4)| = 6
The answer is fill its tanks with air so it floats to the top, but I will solve for the distance since I am nice
so we do
decent means negative
cimb=positive
add
decends 45 and 1/2
-45 and 1/2
climbs 39
+39
decedns 18 and 3/4
-18 and 3/4
add
-45 and 1/2+39-18 and 3/4
add
convert 1/2 to 2/4
gropu negatives
-45 and 2/4-18 and 3/4+39
add
-63 and 5/4+39
-64 and 1/4+39
-25 and 1/4
that is how far dow the submarine is
so the submarine needs to gu 25 and 1/4 ft up to reach the csurface
1st you need to fine the slope using
S = y2-y1/x2-x1
S = -6 - 3/2-2
S = -9/0
S = Undefined
when we have undefined slope the equation would be a vertical lines.
Thus the equation would be the x value of the point
Thus the equation is x = 2
