We have been given a system of equations and we are asked to write correct coefficient matrix for this system.
Since we know that a matrix for a system of equations is in the form: , where A represents the coefficient matrix, X is variables''s matrix and B is the constant matrix.
We are given two equation and two unknown variables, so our coefficient matrix will be a matrix. Our matrices for variable and constant will be of dimensions
(column matrix).
We can represent our given system of equations in matrix form as:
Now let us find our A, X and B parts from above matrices.
Since we know that A represents coefficient matrix, therefore, correct coefficient matrix for our system of equations will be,
Answer:
The remaining length of the candle varies from 8 inches to 4.5 inches.
The required expression is:
Where, b represents the burned length and r represents the remaining length.
Step-by-step explanation:
Consider the provided information.
A 12-inch candle is lit and steadily burns until it is burned out.
The length of the candle is 12 in.
The burned length of the candle is 4 in.
That means the remaining length is 12 - 4 = 8 in
The burned length of the candle is 7.5 in.
That means the remaining length is 12 - 7.5 = 4.5 in
Hence, the remaining length of the candle varies from 8 inches to 4.5 inches.
Suppose b represents the burned length of the candle in inches (or the number of inches that have burned from the candle since it was lit) and r represents the the remaining length of the candle (in inches).
The required expression is:
