What is the exact solution to the system of equations shown on the graph? A.) (-1 3/5, 4 1/5) / B.) (-1 1/5, 4 3/5) / C.) (-1 5/6, 6 2/3) / D.) (-1 1/5, 4 5/6) /

The answer is B.) (-1 1/5, 4 3/5)  /  

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
