Y=3x^2+3x-5. and 2x-y=3
x=-.8 so y=4.6
        
                    
             
        
        
        
Upwards because a is one and therefore positive
        
                    
             
        
        
        
Answer:
5t = 4b 
Step-by-step explanation:
Here, we want to write a proportional relationship for b in terms of t
From the question, b represent the amount of candle burned away in a given time t hours 
From what we have initially, 13 3/4 burnt in 11 hours 
So in 1 hour, the amount burnt will be;
55/4/11 = 5/4 
5/4 inches of candle burnt in 1 hour 
5/4 inches = b/t 
So b inches burnt in t hours 
5/4 = b/t
5t = 4b 
 
        
             
        
        
        
7×20 and 7×2000 are similar. The amount of zeros are the dependent factor.
7×20= 140
7×2000= 14000
The base equation is 7×2=14
Any additions of zeroes in this formula will be added at the end result.
Ex.
7×2=14
7×20=140
7×200=1400
70×200=14000
700×200=140000
        
             
        
        
        
Answer:
The picture has a pattern. The pattern in this picture is that each time 4 corners are added. You can also look at this as it adds 4 each time or as the equation. Y=5+4x. Y being The amount of cubes in the equation
