Answer:
- Switch positions of two rows.
- Add elements of one row to another row.
- Multiply elements of one row by a scalar
Step-by-step explanation:
In general, each row represents a linear equation. The rules of equality apply. They allow you to multiply both sides of the equation by a scalar, add equal values to each side of the equation (add one row to another). Rearranging the sequence of equations (swapping rows) does not change the system or its solution.
Assuming your system of equations is
The answer is C. Infinitely many solutions. If my assumption is incorrect, then the answer will be likely different.
The reason why it's "infinitely many solutions" is because the first equation is the same as the second equation. The only difference is that everything was multiplied by -1. You could say that both sides were multiplied by -1.
Both equations given graph out the same line. They overlap perfectly yielding infinitely many solution points on the line.
Integrate both sides with respect to <em>x</em> :
On the right side, integrate by parts with
Then
Integrate both sides with respect to <em>x</em> by parts again, this time with
Then
