after swimming 80 ft below the surface of the water a whale swims of 40 ft using a number line to help you create an equation that shows the location of the well and relation to the water surface

Respuesta :

We have a whale that swims 80 ft below the surface and then goes up 40 ft.

We can describe her trajectory from surface (y=0) to 80 ft below (y=-80) and then 40 ft up (y=-80+40=-40).

The correct interpretation is Option D: the equation is -80+40=-40. The whale is 40 ft below the surface.
