Question

write the set of all natural numbers X such that 4x+9<50 in roaster form​

Answer 1

Answer:

X = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

Step-by-step explanation:

$4x + 9 < 50 \\ or, 4x < 41 \\ or, x< 10.25$

Answer 2

Given,

X is set of all natural numbers such that $\[4x + 9 < 50\]$

Solution,

Put the values of x start from x = 1 up to x = 10.

It will satisfy the given algebraic condition.

But,

$\[\begin{array}{l}at\,x = 11,\\4x + 9 < 50\\ \Rightarrow 4 \times 11 + 9 < 50\\ \Rightarrow 53 > 50\end{array}\]$

It is not satisfying algebraic expression at x = 11.

Hence x values from 1 to 10 satisfy the given condition.

Set of natural numbers in roaster form,

$\[N = \left\{ {1,2,3,4,5,6,7,8,9,10} \right\}\]$

Hence the set of natural numbers in roaster form is $\[N = \left\{ {1,2,3,4,5,6,7,8,9,10} \right\}\]$
