Yes 4.47 is a rational number
<span>2x-y=6
x+y=6
-------------
3x = 12
3x/3 = 12/3
x = 4
x + y = 6
4 + y = 6
4-4 +y = 6 -4
y = 2
Check
2x - y = 6
2(4) - 2 = 6
8 - 2 =6
6=6

Answer:
slope = -1
Step-by-step explanation:
y2-y1 / x2-x1=
1+5 / -2-4 = 6/-6
M = -1
None of the answers are correct because it’s definitely not “Given” because x=20 is like an answer. It’s also not “Distributive Property”, “subtraction Property”, and or “Additional Property” b/c there’s nothing that can be distributed, subtract or add. It’s just an answer.
