The orderd pair (2,-4) is a solution of which system

answer:its just a matter of subbingand for it to be a solution, it has to satisfy both inequalities.

y < = x + 2(-2,-4)x = -2 and y = -4

-4 < = -2 + 2

-4 < = 0 (true)

y > = x - 3(-2,-4)...x = -2 and y = -4

-4 > = -2 - 3

-4 > = -5 (true)

ur answer is the last one

Step-by-step explanation:

{3 + i, 3 - i, 3, -1}

step-by-step explanation:

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
