Answer:
x=-5, y=5 or (-5,5)
Step-by-step explanation:
We can do elimination with this
this means we should first multiply -5x-4y=5 by 2
this would make it -10x-8y=10
we can now subtract this from the original equation
-8x-8y=0 - (-10x-8y=10)
the ys would cancel out
so this would equal
2x=-10
x=-5
now we can plug this back into the equation to find y
-8(-5)-8y=0
40-8y=0
-8y=-40
y=5
divide feet by seconds
644.8 / 31 = 20.8 feet per second
