Answer:
4th option
Step-by-step explanation:
The relationship is linear,
putting the value of x in the right side of the equation of option 4, you'll get the value of the left side
putting, x=1
y+4=-1/2(x-1)
y=-1/2(1-1)-4
y=-4
putting, x=7
y+4=-1/2(7-1)
y=-1/2(6)-4
y=-6/2-4
y=-3-4
y=-7

X/y
x=1 when y= 5
x=2 when y =10
the constant of proportionality = 1/5
        
             
        
        
        
The third set is equivalent to
2x + y = 2
2x + y = -2
clearly inconsistent.
        
             
        
        
        
The first one 
You start at -2 and go up 1 and to the right 1
        
                    
             
        
        
        
Answer: 4%-16000 and 9.5%-30000
Why:
1) x+y=46000
x=46000-y
2) 4%x+9,5%y=3490;
4x + 9.5y=349000; so 4*(46000-y)+9.5y=349000;
5.5y=165000
y=30000
x=46000-30000=16000
 
        
             
        
        
        
Answer:
If the complement of an angle is 25 degrees, then the measurement of the angle will be 65 degrees.
