Answer:
Option (c) is correct.
Add a constant to a row does not involves while solving a system of equations using matrix.
Step-by-step explanation:
Given : solving a system of equations.
W have to choose from given options that can not be used on a matrix when solving a system of equations.
Since solving the system using matrix method involve
1) adding of rows,
2) multiplying a row by a constant.
3) interchange rows
But add a constant to a row does not involves while solving a system of equations using matrix.
Thus, Option (c) is correct.

Answer: The coordinates that represent a point in the solution set of the system of inequalities shown below is ( -3, 10 )
Step-by-step explanation:
Let assume y = x + 13 ..... (1)
4x + 2y > 3
2y > - 4x + 3
y > -2x + 3/2
Substitutes y in equation 1 into the above equation
x + 13 > -2x + 3/2
x + 2x > 3/2 - 13
3x > (3 - 26)/2
x > -23/6
- 3 is greater than the value above.
Substitute -3 for x in equation 1
y = -3 + 13
y = 10
The coordinates that represent a point in the solution set of the system of inequalities given above can be ( -3, 10)
Answer: Choice C
We can rotate the figure 180 degrees so that it lines up with its original image perfectly. In other words, the before and after would be identical images.
