Let length be l and breadth be b.
l = 4b. (I)
Perimeter: 12.5 km
Perimeter, P = 2(l+b)
P = 2( 4b +b) = 12.5
4b + b = 12.5/2
5b = 6.25
Therefore, b = 6.25/5
= 1.25 km
Now, from 1,
l = 4*1.25
= 5 km
Area = l*b
= 5*1.25
= 6.25 km^2
Plug in 2 for x. f(20=2-51 = -49
The two slopes of the two equations are 2 and 3 respectively. They are the values just to the left of the x. Since the slopes are different, this means the lines are angled so that they are not parallel.
Non-parallel lines will cross exactly one time. So there is exactly one solution.
