Answer:
1.8m^2 approx
Step-by-step explanation:
Given data
P1= 1400N
A1=0.5m^2
P2=5000 N
A2=??
Let us apply the formula to calculate the Area A2
P1/A1= P2/A2
substitute
1400/0.5= 5000/A2
cross multiply
1400*A2= 5000*0.5
1400*A2= 2500
A2= 2500/1400
A2= 1.78
Hence the Area is 1.8m^2 approx
 
        
             
        
        
        
So if you want it to be 9 less than your number (x) then you would subtract nine. 
 So it would be: 
 x - 9. 
 So if your "number" is 12 then you would substitute x for 12 and it would be 12-9. The answer is 3. So 3 is 9 less than a number (12).

The answer is 2 hopefully this helped
        
             
        
        
        
You can soustracte the first or the second one 
and y cancel 
x = 6
now you put 6 in x
you can take the first or the second one 
6 - y = -2
6 - y = -2
y = -8
        
             
        
        
        
Answer:
y = -1/2x - 3
Step-by-step explanation:
slope: (y2-y1) / (x2-x1)
(-5 - -2) / (4 - -2)
(-5 + 2) / (4 + 2)
-3 / 6
- 1 / 2
y-intercept: y = mx + b
-5 = -1/2(4) + b
-5 = -2 + b
-3 = b
