Answer:
80°
Step-by-step explanation:
Since they are vertical angles, they are congruent to each other.
∠r ≅ 80°
 
        
                    
             
        
        
        
Answer:
3√2 or 4.24
Step-by-step explanation:
d(w,x) = √(5-2)² + (-4-(-7))² = √18 = 3√2               (4.24)
 
        
             
        
        
        

So y=2x is the only answer that fit y=kx, while k=2
 
        
             
        
        
        
Answer:
How the zero product property applies to solving quadratic equations?
The zero product property states that if the product of two quantities is zero, then one or both of the quantities must be zero. ... When you factor, you turn a quadratic expression into a product. If you have a quadratic expression equal to zero, you can factor it and then use the zero product property to solve.

Answer:
The correct equation is "y=30x+6147". A further explanation is given below.
Step-by-step explanation:
The given values are:
(x1, y1) = (50, 7647)
(x2, y2) = (100, 9147)
As we know,
The slope is,
⇒ 
On substituting the given values, we get
⇒     
⇒     
⇒     
Now,
⇒ 
On substituting the given values in the above equation, we get
⇒ 
⇒ 
On adding "7647" both sides, we get
⇒ 
⇒
