Answer:
1. the y-intercept is 9.5 and it means the starting length of the candle
2. the slope is -1/2 and it means that the candle burns 1/2 an inch every hour
3. it burns an inch every 2 hours, it is 9.5 inches long, so 19 hours it'll take to burn.
Answer: x=17, y=45
Explanation: Let the numbers be x and y.
We have,
3x−6=y
Also, x+y=62
Thus, x+3x=62+6
Or, x=17
Putting in the required values, we get y as 45
Answer:
Step-by-step explanation:
The given equation is A=4 πr².
We need to solve the above equation for r².
We have,
A=4πr²
Dividing both sides by 4π, we get :
Hence, the value of r² is equal to 
.
