V(x) = (2x - 3)/(5x + 4) 
The domain is all Real numbers except x = -4/5, because if x = -4/5 the denominator would be zero and you cannot divide by zero.
{x | x ∈ R, x ≠ -4/5}
w(x) = (5x + 4)/(2x - 3)
similarly, x ≠ 3/2
so, {x| x ∈ R, x ≠ 3/2}
        
                    
             
        
        
        
The answer is by using the measuring tape
        
             
        
        
        
Becouse k and n are 'neighbours' so their sum are 180
so k=180-42=138
        
             
        
        
        
Answer:
x = 110°
Step-by-step explanation:
Given that AB = AD then Δ ABD is isosceles and the base angles are congruent, that is
∠ ABD = ∠ ADB = 35°
The sum of the 3 angles in the triangle = 180°, that is
x + 35° + 35° = 180°
x + 70° = 180° ( subtract 70° from both sides )
x = 110°
 
        
             
        
        
        
X + (-y) = -2.3 + ( - (-5.9) ) = -2.3 + 5.9 = 3.6
