Answer:
q=6
Step-by-step explanation:
A root can be plugged in for X, so 2(2)-5(2)+q=0. This means -6+q=0. We can now even them out and know q=6
 
        
                    
             
        
        
        
Y=-7/2x+1/2
1. find slope
2. plug in slope to y=mx+b
3. take point and plug it in (find a b)
4. plug in slope and b to get equation
        
                    
             
        
        
        
Just do a line crossing another in a angle of 90°
1 is linear pair with 2, 2 is linear pair with 3, 3 is linear pair with 4 and 4 is linear pair with 1.
 
        
             
        
        
        
Step-by-step explanation:
by comparing both f (x) and g (x) 
we get
3x-1=2x-1/x
by this way we can get the value of X and put the value of X in f (x) and g (x)
 
        
             
        
        
        
Answer:
Step-by-step explanation:
<u>The scale factor is:</u>
Applied to the area we consider k² as the area is the product of two dimensions.
<u>Find the actual area:</u>
- 0.25 m² : (1/400)² = 
 - 0.25 m² * 160000 = 
 - 40000 m² = 
 - 40000 * 1/10000 hectares = 
 - 4 hectares
