Question #6077

Which ordered pair is NOT a solution of the inequality y < 3 – 2x?
(-1, 3)
(6, -7)
(0, 4)
(-4, 5)

Expert's answer

first pair

3 < 3 - 2(-1)

3<5 is a solution.

Second pair

-7 < 3 - 2*6

-7 < -9 is NOT a solution

Third pair

4 < 3 - 2*0

4 < 3 is NOT a solution

Forth pair

5 < 3 - 2*(-4)

5 < 11 is a solution

So solution are the next pairs: (6, -7) (0, 4)

3 < 3 - 2(-1)

3<5 is a solution.

Second pair

-7 < 3 - 2*6

-7 < -9 is NOT a solution

Third pair

4 < 3 - 2*0

4 < 3 is NOT a solution

Forth pair

5 < 3 - 2*(-4)

5 < 11 is a solution

So solution are the next pairs: (6, -7) (0, 4)
