Because JKL is a right triangle, it has an area formula of (a*b)/2 (in which a and b are the legs of the right triangle).
(13 ft* 4ft) /2= 26 ft^(2).
The area of JKL is 26 ft^(2).
Hope this helps~
Answer:
4
Step-by-step explanation:
Area of the figure:
Af = a² + 2 a²/4 π = 2.57 a²
Area of the shaded region:
As = 2 a²/4 π = 1.57 a²
x = (1.57 · 100) / 2.57 = 61 % ≈ 60 %
Answer: B) about 60 %
Answer:
im pretty sure its -1

Answer:
We see two intersecting lines.
It means there is one solution, it is the intersection point.
Solution is (3, 4)
It was easy to find the solution as both lines and their intersection is visible on the graph.
With two parallel lines we would have no solutions and with overlapping lines we would have infinitely many solutions.
If you only have the equations of the lines you need to compare the slopes, if they are different it means lines are intersecting at one point hence one solution.
With same slopes and different y-intercepts there is no solution.
With same slopes and y-intercepts there is infinitely many solutions.
