Please make it a little more understandable
Answer:
2x^3+2x-1
Step-by-step explanation:
If submarine is at the surface (the initial position) and then dives 375 ft, the coordinate of submarine becomes -375 ft <span>relatively to the initial position. When the submarine dives another 175 ft down, the coordinate of submarine becomes -375-175=-550 ft relatively to the initial position.

Answer: Correct choice is A.
<span />
Simplify y=8x+2x+2: y=10x+2
Same as equation y=10x+2
Therefore it has infinitely many solutions
7/7.42 = $0.94
Hope this helped :)
