First of all: subtract 3 from 3x then from 2y then divide
        
                    
             
        
        
        
Answer:
y = 5x2 + 10x - 15
 
We want this in format y = a(x-h)2 + k
where the vertex will be at (h,k)
 
y = 5(x2+2x) - 15
Complete the square on x2+2x
 
y = 5(x2+2x+1) - 15 - 5
We subtract 5 at the end because we are actually adding 5(1) = 5
so we need to remove it also to keep the total equal
 
y = 5(x+1)2 - 20
 
The vertex is at (-1,-20)
 
        
             
        
        
        
You use the slope formula, (y2-y1/x2-x1)
 
        
             
        
        
        
If its nonsense question well i don't know
please don't give nonsense question.
 
        
                    
             
        
        
        
the answer is 75 minutes/1h 15m
15 pages × 350 words = 5250 words
5250 ÷ 70 = 75 minutes (1h 15m)
hope this helps!!
