To find the slope, use the simple rule rise/run. The change in the y value over the change in the x value. The y changes by -1 when the x changes by positive 2. Therefore, the slope is -1/2.
        
             
        
        
        
Answer: w ≤ 14 cm , L ≤ 42 cm
<u>Step-by-step explanation:</u>
width (w): w
Length(L): 3w
Perimeter (P) = 2w + 2L
P ≤ 112
  2w +   2L   ≤ 112
2(w) + 2(3w) ≤ 112
  2w +   6w   ≤ 112
        8w        ≤ 112
          w        ≤ 14
 
        
             
        
        
        
The percent would be 29%. You need to move the decimal to the right twice.
        
                    
             
        
        
        
Answer:
3x-2
Step-by-step explanation:
JK =JL+LM
5x-8=JL +(2x -6)
JL = 5x-8 -2x+6
JL = 3x-2
