Yes it is the solution of the system
Answer:
x is less than or equal to 3
Step-by-step explanation:
The dot is a closed dot, which means that it is something or equal to, and the arrow is pointing down, which means less than. So the sign would be less than or equal to (sorry I don't have that sign on my computer). The dot is on three, so the inequality is x is less than or equal to 3.
0.5x + 0.75y = 130
x + y = 200
now use system of equations to find that x = 80 and y = 120
