Yes it would be reasonable because the amount of gas in his car DECLINES which makes it a negative association.
+5 on both sides
So you're left with 2x=33
Divide 2 from both sides
X= 16.5
Answer: 100 times greater
Step-by-step explanation:
2x + 3y = -21
2x = -21 - 3y
x = -10.5 - 3/2y
-10x + 2y = 20
-10(-10.5 - 3/2y) + 2y = 20
105 + 15y + 2y = 20
105 + 17y = 20
17y = -85
y = -5
2x + 3y = -21
2x + 3(-5) = -21
2x - 15 = -21
2x = -6
x = -3
Therefore, the coordinates are (-3, -5).
