Answer:
(-∞,0)
Step-by-step explanation:
Graph y=|x| 
Note that the graph is shaped like a V. The left half of the graph is decreasing from -∞ up until 0 when it hits the origin and starts to increase. Put this into interval notation: (-∞,0).
 
        
                    
             
        
        
        
The answer is A. for this, you have to set up a system of equations. the first one will be the area equation. since you know area=length x width, your equation will be LxW=50. the next equation is L=2W, since the length is two times the width. then, plug in 2W for the L in the other equation and you get 2W^2=50. divide by 2 and get W^2=25. square root both sides and you get W=5. plug back into the other equation to find L=10. Then, add the sides of the rectangle for the perimeter. 10+5+10+5=30.
        
             
        
        
        
Answer:
4/11
Step-by-step explanation:
We can find the slope using the slope formula
m = ( y2-y1)/(x2-x1)
     = ( 1 - -3)/(7 - -4)
      = (1+3)/(7+4)
     = 4/11
