X - 3y = -8
x + 3y = 8
--------------- Add the equations
2x = =
x = 0
Plug zero back in to either equation and solve for y.
x - 3y = -8
0 - 3y = -8
-3y = -8
divide both sides by -3
y = 8/3
(0, 8/3)
ONE SOLUTION
First draw sloping up (steep because he’s running)to the right until you hit 20 on the y axis. Next draw down and to the right for 5 yards until 15 on y axis. Next is a flat horizontal line for 3 seconds on x axis. Finally a shallow slope line down (because he is walking) and right until you hit the x axis.
it’s hard to explain so look at the picture i attached to this :)
Answer:
I am pretty sure the answer is 324 or 300
