Is (1, 2) a solution of the system y > 2x and x+y< 3? select one: a. yes, because (1, 2) is a solution to both inequalities. b. yes, because (1, 2) is the point of intersection of the two boundary lines of this system. c. no, because (1, 2) is a solution to only one of these inequalities. d. no, because (1, 2) is not a solution to either inequality.

d

Step-by-step explanation:

To determine if (1, 2) is a solution to the system

Substitute x = 1, y = 2 into the inequalities and check their validity.

y > 2x → 2 > 2 ← incorrect statement

x + y < 3

1 + 2 < 3 → 3 < 3 ← incorrect statement

(1, 2) is not a solution to either inequality → d

i believe the correct answer is option 4.principalities were small territories that were run by russian rulers.

which statement correctly defines principalities in northern asia in the 1200s? principalities were small territories that were run by russian rulers.

hope i could ! : )
