A. would have the highest pitch because the sound vibration are close together and it would also be the fastest. B is incorrect because the sound waves are very which would give it a deeper voice and it would be the slowest 
Hope this helps
        
             
        
        
        
Answer:
 x+
x+ y+5=0
y+5=0
Step-by-step explanation:
the intersection of x-2y=0 and 3x+y+5 is ( ;
; )
)
=> the line :  x+
x+ y+5=0
y+5=0
 
        
                    
             
        
        
        
A farm had 480 acres more wheat than corn. Let use "W" to represent the Wheat and let use "C" to represent the corn. Hence, we have below:
W=C+480
The farmers collected 80% of the wheat and 25% of the corn and the area of the wheat is 300 acres less than the area of the corn:
W-0.8W=C-0.25C+300
0.2W=0.75C+300
We have two equations, two unknowns:
0.2(C+480)=0.75C+300
0.2C+96=0.75C+300
0.55C=294
C=534.55
        
                    
             
        
        
        
Explanation:
x + 3y = 2
<u>Converting it to slope intercept form</u>:
y = mx + b  [where m is slope, b is y-intercept]
<u>Make y the subject</u>:




<u>which reveals slope</u>:
