Consider the following inequalities.
(i) $2x - 1 > 7$
(ii) $2x - 9 < 1$
Which one of the following expressions below satisfies the above two inequalities?
We need to solve the first inequality:
$2x - 1 > 7$
So, the solution for the first inequality is $x > 4$.
Next, we solve the second inequality:
$2x - 9 < 1$
The solution for the second inequality is $x < 5$.
We need a value of $x$ that satisfies *both* inequalities simultaneously. This means $x$ must be greater than 4 AND less than 5.
Combining $x > 4$ and $x < 5$ gives the combined inequality:
$4 < x < 5$
Now, compare this result with the given options:
The expression $4 < x < 5$ exactly matches Option 3.
A stick of length one meter is broken at two locations at distances of $b_1$ and $b_2$ from the origin (0), as shown in the figure. Note that $0 < b_1 < b_2< 1$. Which one of the following is NOT a necessary condition for forming a triangle using the three pieces?
Note: All lengths are in meter. The figure shown is representative.
