Answer: y= -2x/12+2
Step-by-step explanation:
12y=-2x+24
y= -2x/12 +2
Let a, b, c, d be coefficients for the balanced reaction:
a HC₂H₃O₂ + b KNO₂ → c KC₂H₃O₂ + d HNO₂
Count the elements among the reactants and products:
H: 4a = 3c + d
C: 2a = 2c
O: 2a + 2b = 2c + 2d
K: b = c
N: b = d
Suppose we let b = 1. Then both c = 1 and d = 1, and in the O equation we have
2a + 2 = 2 + 2 ⇒ 2a = 2 ⇒ a = 1
(Note that the equations for H and C also hold up.)
So the balanced reaction is simply
1 HC₂H₃O₂ + 1 KNO₂ → 1 KC₂H₃O₂ + 1 HNO₂
Answer:
grams maybe
Step-by-step explanation:
I believe you're asking about the one-sided limit,
Recall the definition of absolute value:
• 
if 
• 
if 
Since we're approaching -4 from the left, we're effectively focusing on a domain of 
or 
. So, by the definition above, we have 
. Then in the limit, we have
