(16 - 4) ÷ 2
This would give you $6, so that is how much they expect you to spend per meal.
        
             
        
        
        
Answer:
A linear function has the form y=mx+b
A line has a proportional relationship if y/x is always the same ratio for any value.
The slope m=(y2-y1)/(x2-x1) for some two points on a line is always constant, else it wouldn't create a line.
A line won't be proportional if you adapt b because the ratio of y/x won't match the slope anymore.
In the end this means all lines with proportional relationships must intersect (0,0) or in other words f(0)=0.
This happens if they have the shape y=mx.

Answer:
This has one real solution, x=4
Step-by-step explanation:
 8 - 4x = 0
Add 4x to each side
 8 - 4x+4x = 0+4x
8 =4x
Divide each side by 4
8/4 = 4x/4
2 =x
This has one real solution, x=4
 
        
                    
             
        
        
        
The distance formula is d=√(x2-x1)² + (y2-y1)²
So... d =8.06226
Hope this helps
 
        
             
        
        
        
It depends on which variable is eliminated.
If you multiply the second equation by -1 and eliminate the y:
3x - y = 7
-6x + y = -10
-3x = -3 or x = 1
 
If you multiply the first equation by -2 and eliminate the x:
-6x + 2y = -14
6x - y = 10
y = -4
