Answer:
{ (0, 0), (4, 0), (6, 0) }
Step-by-step explanation:
In order to be a function, ordered pairs must have values of x, or the domain, that are different and do not repeat. 
 
        
             
        
        
        
Answer:
12.94
Step-by-step explanation:
By the law of sines:
x / sin(35) = 7.9 / sin70 
x = 7.9 * sin(70)/sin(35)
= 7.9 * 0.9397 / 0.5736
= 12.94
 
        
             
        
        
        
Answer:

Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form  or
 or  
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
In this problem we have 

Substitute the values and solve for k


therefore
the equation of the line is equal to
