Answer:
y=(x+5)²-3.
Step-by-step explanation:
1) the coordinates of the vertex are (-5;-3), it means (x+5)², not (x-5)²;
2) the vertex of the given graph is in bottom side, it means no minus before the '(x+5)';
3) according the items 1 and 2 and the given answers, the correct answer is y=(x+5)²-3.

Answer:
Medium: 4 and Large: 6
Step-by-step explanation:
Factor pairs that are equivalent to 10:
1,9
2,8
3,7
4,6
5,5 
and so on. So you could do 2.4*9 and 1.8*1. If that doesn't work, switch it around. This coud probably take 1/2 of a hour or more. But it'll be worth it if it's a grade. :3 
In the end, I'm pretty sure you should be able to get the answer:
Medium cups: 4
Large cups: 6
1.8 multiplied by 4 would get you 7.2 and 2.4 multiplied by 6 would get you 14.4. If you add them all up, you would get a 21.6! If you didn't, check your math again. 
 
        
                    
             
        
        
        
a is a point, b is a line (extends forever in both directions) and c is a ray (extends forever in one direction)
