Step-by-step explanation:
A candle 6 inches high burns at a rate of 1 inch every 2 hours for 5 hours. The candles burning rate is 0.5 inch per hour).
Then
- a cnadle height after first hour is 6 - 0.5 = 5.5 inches;
- a candle height after first two hours is 5.5 - 0.5 = 5 inches;
- a candle height after first three hours is 5 - 0.5 = 4.5 inches;
- a candle height after first 4 hours is 4.5 - 0.5 = 4 inches;
- a candle height after first 5 hours is 4 - 0.5 = 3.5 inches.
The candles height h (in inches) at any time t (in hours) is modeled by

Answer:
15x-8=0
x=8/15
Step-by-step explanation:
The correct answer is:
A. 14x+6y= 10
-14X-35y=77
Further explanation:
One method of solving system of linear equations in two variables is elimination method. In this method, the co-efficient of one variable have to be equated so that variable can be removed to get the value of other variable.
Given equations are:
As we have to eliminate x, then the co-efficient of x will be equated. For this purpose both equations will be multiplied with some constant.
So,
multiplying equation one with 2
Multiplying equation 2 by -7
So,
The correct answer is:
A. 14x+6y= 10
-14X-35y=77
