409,200,000,000= 4.092 × 10^11
Answer:
it is a or d
Step-by-step explanation:
Answer:
x = 3, y = -4
Explanations:
The given system of linear equations is:

The graph representing the equations is plotted below:

The point where both lines intersect is the solution to the system of equations.
The lines intersect at the point (3, -4), therefore, (3, -4) is the solution to the system of equations
