Answer:
1 and 2.....then 3 is a different question
Answer:
The y-intercept is 12.
It represents the original length of the candle.
Step-by-step explanation:
y = 12 - 0.2x
y = 0.2x + 12
y = mx + b
b is the y-intercept.
b = 12
The y-intercept is 12.
It represents the original length of the candle.
Add 15 to the other side of the equation which gives you 15 and then do 15/7 which gives you 2.14 when you round it so x=2.14
10/12, 15/18, 20/24, 25/30, 30/36
I believe the answer is : Y=2(x+5)^2-51
