Answer:
2.5 hours
Step-by-step explanation:
We are given that
Original height of candle=5 in
Every hour candle loses =8% of 5 in=0.4
According to question
Subtract 4 from both sides we get
Divide by 0.4 on both sides
x=2.5 hours
Until the candle has been burning for at least 2.5 hours, the height of her candle will be more than four inches.
6 km is larger than 54,000 mm
To find the x-intercept, plug zero into y and solve for x.
2x+3(0)=-18
2x=-18
/2 /2
x=-9
To solve for the y-intercept, do the same thing, but instead plug zero into the x-intercept to solve for y.
2(0)+3y=-18
3y=-18
/3 /3
y=-6
So, your answer to your question is the y-intercept=-6, and the x-intercept=-9

Answer:
The discount which she received is 25 %
