Answer: I think it's X^5/3Y^1/3
Answer: y-4x > -6
Step-by-step explanation: Y-4x is 4x is positive and if you are above the Zero on a negative and positive chart the positives are always higher then the negatives.
The answer would be b because if you substitute 5 in for x y=2x-6 would equal 4 and y=5x-21 would equal 4. I hope this helps!
I am pretty sure its B (minimum at -1, -4) because that would be were the first point would be at. The Graphing of this equation would be a "upside down u" shape.
