Answer:
D irrational number
Step-by-step explanation:
because you do the Pythagorean theorem and you get 7.81024976 and that is a irrational number
y = 0.5
x = 4 - y (0.5)
3.5 = 4 - 0.5
------------
3x - 10 = y
3(3.5) - 10 = y
10.5 - 10 = y
0.5 = y
Nice!
HAHAHAHA "1" "2" "3" "4" OMG THAT MAKES SENSE!
