Answer: -70
I think it is -70 because the submarine was 120ft bellow sea level which is -120. Now if it climbs 50ft towards sea level it means that it goes up 50ft so add 50 to the -120.
-120+50= -70

Answer: 
Step-by-step explanation:
1. By definition, if
when
, then:

2. Keeping this on mind, to find the value of
when
, you must apply the following proccedure:

3. Now, you must solve for
, as following:

4. Then, the result is:

Answer: x = 6, the y - coordinate is 4, therefore the value of the function when x = 6 is 4.
For perpendicular lines, m2 = -1/m1.
For line -x + 5y = 14 => 5y = x + 14 => y = 1/5 x + 14/5 => slope = 1/5
m2 = -1 / (1/5) = -5
Required equation is y - (-2) = -5(x - (-5))
y + 2 = -5(x + 5)
5x + y = -25 - 2
5x + y = -27
