Answer:
B
Step-by-step explanation:
hope this help but I worked it out so it should be true
3 kilometers is equal to 3000 meters
Distance of a ground is 300 meters sou need to run 10 rounds around thefield
True I’m not sure I’m just guessing cause I gotta answer Two questions before mine
1: (-1,-1) is (x, y) to see if it is a solution, you would just plug in x and y and see if the equation is true.
-4 (-1) + 2(-1) = 2
4 + -2 = 2
2 = 2 CORRECT
So... plug in x and y in the second equation to Make sure it works for that one too.
-1 + -1 = -2
-2 = -2 CORRECT
So, yes. (-1,-1) is a solution to both equations.
You can tell by using the time tables
