True or False?

Is [tex]$(-4,-6)$[/tex] a solution to the system:
[tex]\[
\left\{
\begin{array}{l}
y \leq 3x + 2 \\
y \ \textgreater \ x - 1
\end{array}
\right.
\][/tex]

A. True
B. False


Sagot :

To determine whether the point [tex]\((-4, -6)\)[/tex] satisfies the system of inequalities

[tex]\[ \left\{\begin{array}{l} y \leq 3x + 2 \\ y > x - 1 \end{array}\right. \][/tex]

we need to check if this point satisfies both inequalities.

1. First inequality: [tex]\( y \leq 3x + 2 \)[/tex]

Substitute [tex]\(x = -4\)[/tex] and [tex]\(y = -6\)[/tex]:

[tex]\[ -6 \leq 3(-4) + 2 \][/tex]

Simplify the right-hand side:

[tex]\[ -6 \leq -12 + 2 \][/tex]

[tex]\[ -6 \leq -10 \][/tex]

This is false since [tex]\(-6\)[/tex] is not less than or equal to [tex]\(-10\)[/tex].

2. Second inequality: [tex]\( y > x - 1 \)[/tex]

Substitute [tex]\(x = -4\)[/tex] and [tex]\(y = -6\)[/tex]:

[tex]\[ -6 > -4 - 1 \][/tex]

Simplify the right-hand side:

[tex]\[ -6 > -5 \][/tex]

This is false since [tex]\(-6\)[/tex] is not greater than [tex]\(-5\)[/tex].

Since the point [tex]\((-4, -6)\)[/tex] does not satisfy either of the inequalities, it does not satisfy the system of inequalities.

Therefore, the answer is [tex]\(\boxed{False}\)[/tex].
