Answer:
2.5 meters per second
Step-by-step explanation:
75/30 = 2.5
I'd choose 25 because the person who wrote the answers probably forgot to add decimal points
Answer: You find midpoint by adding the two x values together and dividing by 2, then adding the two y values together and dividing by two.
You need to isolate the variables. For the first equation add x to both sides, which leaves you with y.
For the second equation, divide each side by 2 leaving you with
x= 6+y. Subtract y from each side. Subtract x from both sides. Now you have y= x + 6.
Now graph those equations.
