Which ordered pair is in the solution set?

[tex]\[
\begin{array}{c}
y \ \textgreater \ -3x + 4 \\
y \leq 3x - 2
\end{array}
\][/tex]

A. [tex]$(2,1)$[/tex]
B. [tex]$(1,-2)$[/tex]
C. [tex]$(0,4)$[/tex]
D. [tex]$(1,3)$[/tex]



Answer :

To determine which ordered pairs satisfy both of the given inequalities:

[tex]\[ \begin{array}{c} y > -3x + 4 \\ y \leq 3x - 2 \end{array} \][/tex]

Let's analyze each ordered pair individually.

1. Ordered pair [tex]\((2,1)\)[/tex]:

- Check the first inequality [tex]\(y > -3x + 4\)[/tex]:
[tex]\[ 1 > -3(2) + 4 \][/tex]
[tex]\[ 1 > -6 + 4 \][/tex]
[tex]\[ 1 > -2 \quad \text{(True)} \][/tex]

- Check the second inequality [tex]\(y \leq 3x - 2\)[/tex]:
[tex]\[ 1 \leq 3(2) - 2 \][/tex]
[tex]\[ 1 \leq 6 - 2 \][/tex]
[tex]\[ 1 \leq 4 \quad \text{(True)} \][/tex]

Both conditions are satisfied for [tex]\((2, 1)\)[/tex].

2. Ordered pair [tex]\((1, -2)\)[/tex]:

- Check the first inequality [tex]\(y > -3x + 4\)[/tex]:
[tex]\[ -2 > -3(1) + 4 \][/tex]
[tex]\[ -2 > -3 + 4 \][/tex]
[tex]\[ -2 > 1 \quad \text{(False)} \][/tex]

Since the first condition is not satisfied, there's no need to check the second condition. [tex]\((1, -2)\)[/tex] is not in the solution set.

3. Ordered pair [tex]\((0, 4)\)[/tex]:

- Check the first inequality [tex]\(y > -3x + 4\)[/tex]:
[tex]\[ 4 > -3(0) + 4 \][/tex]
[tex]\[ 4 > 0 + 4 \][/tex]
[tex]\[ 4 > 4 \quad \text{(False)} \][/tex]

Since the first condition is not satisfied, there's no need to check the second condition. [tex]\((0, 4)\)[/tex] is not in the solution set.

4. Ordered pair [tex]\((1, 3)\)[/tex]:

- Check the first inequality [tex]\(y > -3x + 4\)[/tex]:
[tex]\[ 3 > -3(1) + 4 \][/tex]
[tex]\[ 3 > -3 + 4 \][/tex]
[tex]\[ 3 > 1 \quad \text{(True)} \][/tex]

- Check the second inequality [tex]\(y \leq 3x - 2\)[/tex]:
[tex]\[ 3 \leq 3(1) - 2 \][/tex]
[tex]\[ 3 \leq 3 - 2 \][/tex]
[tex]\[ 3 \leq 1 \quad \text{(False)} \][/tex]

Since the second condition is not satisfied, [tex]\((1, 3)\)[/tex] is not in the solution set.

After analyzing all pairs, the only ordered pair that satisfies both inequalities is [tex]\((2,1)\)[/tex].

Hence, the ordered pair that is in the solution set is [tex]\( (2, 1) \)[/tex].
