Question

Which of the following ordered pairs is included in the solution set of the system, y < 2 - 2x and y > 2x -3?
A. (0, 0)
B. (3, 4)
C. (4, 0)
D. No Solution

Answer 1

I would just substitute for x and y and observe results.
A. 0<2-2(0)
0<2 true for first, now the other equation. 0>2(0)-3, 0>-3 , true so A. is included.

Answer 2

I would check the remaining to see if it has more than one answer

Answer 3

Alrighty ((:

Answer 4

A.(0, 0) only

Answer 5

B. 4 < 2 - 2(3)
4<-4 not true so it ain't B.

Answer 6

C. 0< 2 - 2(4)
0<-6 Not true, so C. is not a solution.
