The smallest common denominator is 30 in so 
<span>9/10=27/30 and 5/6=25/30 are your answers ; ]</span>
        
                    
             
        
        
        
Answer:
No solution
Step-by-step explanation:
The given equations are :
9x-3y=-6 
3x-y=2.....(1)
5y=15x+10
5y-15x=10
or
y-3x=2 .....(2)
Equations (1) and (2) shows that the lines are parallel. We know that for parallel lines, there is no solution. 
 
        
             
        
        
        
Answer:
Rational is the answer

Answer:
Step-by-step explanation:
 
        
                    
             
        
        
        
-16t^2 + v0t + h0
=  -16(t^2 - 1/16 v0t)  + h0
 = -16 [(t - 1/32v0)^2 - (1/32 v0)^2 ) + h0
 = -16(t - 1/32v0)^2 + 1/64 (v0)^2 + h0   which is the vertex form 
The vertex  is at the point (1/32v0, 1/64 (v0)^2)
1/32v0  represents the time  when the firework is at its maximum height and 1/64 (v0)^2  is this maximum height
