Answer:
The answer is below
Step-by-step explanation:
The next step to solve the system, would be to divide the second row by 3 and we would be left with: 3 * R2
[1 -5 3 0 -2
0 1 -7/3 0 4/3
0 0 1 2 -2]
Then what we will do is multiply row 3 by 7/3 and then subtract it from row 2, that is, R2 - 7/3 * R3, and it would look like this:
[1 -5 3 0 -2
0 1 0 14/3 -10/3
0 0 1 2 -2]
And these would be the next two steps in the process of solving the system.
Answer:
No.
Step-by-step explanation:
If (0,5) is a solution to y=2x, then 5=2(0) has to be true.
It is not because 5=2(0) is not true.
2(0)=0 and 0 is definitely not 5.
An example of a point on y=2x is (5,10) since 10=2(5) is true.
