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

maybe b

Answer 2

We know that ordered pairs are given as (x,y) for any function y of x. So, if we have y=f(x), we need to plug in each individual ordered pair to determine which of them work out.

As it happens, A works out.

y(0)<2-2(0) and y(0)>2x(0)-3, so 0<2, and 0>-3.

Both of which are true.

Thus the ordered pair A is the answer.

Answer 3

. y ≥ - x - 1
y < 2x + 2
B. y ≤ -x + 2
y < 2x - 1
C. y < - x - 1
y ≥ 2x + 2
D. y > - x + 2
y ≤ 2x - 1
