Weight of an object=J
x=J/(379.2/150)
x=J/2.528
y=12.64/2.528
y=5
Hope this helps :)
Answer:
feet : Shark is 72 feet below sea level.
Step-by-step explanation:
Let x represent depth of the shark.
We have been given that the submarine’s depth was twice the depth of the shark. This means that depth of submarine would be
.
We have been given that a submarine was 144 feet below sea level, so submarine's elevation would be
.We can represent this information in an equation as:

To find shark's position, we need to solve for x.


Therefore,
feet represents shark's elevation, which represents that shark is 72 feet below sea level.
2nd and 4th are functions
an x value in a set of functions can only have one y value. however, a y value can have infinite amount of x values
in the 1st and 3rd set, the x value of -2 has 2 y values
