Which ordered pair makes both inequalities true?

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

A. (0, 0)
B. (0, -1)
C. (1, 1)
D. (3, 0)



Answer :

To find which of the given ordered pairs satisfies both inequalities, we need to apply each pair to both inequalities and check if they hold true.

The inequalities are:
1. [tex]\( y > -2x + 3 \)[/tex]
2. [tex]\( y \leq x - 2 \)[/tex]

Let's test each of the given pairs:

1. Pair [tex]\((0, 0)\)[/tex]:
- For the first inequality: [tex]\( 0 > -2(0) + 3 \)[/tex]
- Simplifies to: [tex]\( 0 > 3 \)[/tex] (This is false)
- Since the first inequality is not satisfied, we don't need to check the second one.

2. Pair [tex]\((0, -1)\)[/tex]:
- First inequality: [tex]\( -1 > -2(0) + 3 \)[/tex]
- Simplifies to: [tex]\( -1 > 3 \)[/tex] (This is false)
- Since the first inequality is not satisfied, we don't need to check the second one.

3. Pair [tex]\((1, 1)\)[/tex]:
- First inequality: [tex]\( 1 > -2(1) + 3 \)[/tex]
- Simplifies to: [tex]\( 1 > 1 \)[/tex] (This is false)
- Since the first inequality is not satisfied, we don't need to check the second one.

4. Pair [tex]\((30, 0)\)[/tex]:
- First inequality: [tex]\( 0 > -2(30) + 3 \)[/tex]
- Simplifies to: [tex]\( 0 > -60 + 3 \)[/tex]
- Further simplifies to: [tex]\( 0 > -57 \)[/tex] (This is true)
- Second inequality: [tex]\( 0 \leq 30 - 2 \)[/tex]
- Simplifies to: [tex]\( 0 \leq 28 \)[/tex] (This is true)
- Since both inequalities are satisfied, this is a valid pair.

Based on this analysis, the pair [tex]\((30, 0)\)[/tex] satisfies both inequalities. Therefore, the ordered pair that makes both inequalities true is [tex]\((30, 0)\)[/tex].
