What is the final elevation if

A fish starts at -9 meters and changes -11 meters?

Final elevation of butterfly = 4m

Final elevation for diver = -11m

Final elevation for whale= 2m

Final elevation for fish = -20m

Step-by-step explanation:

Final elevation= Initial poistion + Change.

A butterfly starts at 20 m and changes -16 m.

Final elevation = 20m +(-16m)

= 20-16 m   [(-)(+)=(-)]

= 4m

A diver starts at 5 m and changes -16 m.

Final elevation = 5m + (-16) m

= 5m- 16 m  [(-)(+)=(-)]

= -11 m

A whale starts at -9 m and changes 11 m.

Final elevation = (-9m)+11m

= 11m- 9m   [-a+b=b-a]

= 2m

A fish starts at -9 meters and changes -11 meters

Final elevation = -9+(-11) m

= (-9-11) m     [(-)(+)=(-)]

=-(9+11)  m   [-a-b=-(a+b)]

=-20m

Hence, Final elevation of butterfly = 4m

Final elevation for diver = -11m

Final elevation for whale= 2m

Final elevation for fish = -20m

the correct answer to your question is a. 4^4

good luck my friend!

hope this !

maybe if i you could me by giving me brainliest?
