Solution:
If |x| > 5 then, x < -5 or x > 5
$\Rightarrow\text{x}\in(-\infty, -5)\cup(5, \infty)$
Hence, the statement is False.
Solution:
Set of $\text{x}\geq0$
and $\text{x}\leq0$ isHence, the statement is False.
Solution:
The given graph represent $\text{x}\geq3$
Hence, the statement is False.
Solution:
The given graph represent $\text{y}\geq0$
Hence, the statement is False.
Solution:
If xy < - 2 and x > 9, then x have no value.
Hence, the statement is True.
Solution:
If $|\text{x}|\leq4$ then $-4\leq\text{x}\leq4$ $\Rightarrow\text{x}\in[-4, 4]$ Hence, the statement is True.
Solution:
Solution Set of $\text{x}\geq0$ and $\text{y}\leq1$ is
Hence, the statement is False.Solution:
If xy < -5 and x > 2, then x have no value. Hence, the statement is False.Solution:
If xy > 0 ⇒ x < 0 and y > 0 or x < 0 and y < 0 Hence, the statement is False.
Solution:
The given graph represents $\text{x}+\text{y}\geq0$ Hence, the statement is True.Solution:
$\Rightarrow\frac{\text{x}}{\text{b}}>\frac{\text{y}}{\text{b}}$ Hence, statement is False.
