Question

Represent the solution of each of the following inequalities on the real number line:
$1+x\ge 5x-11$

Answer 1

$1+x\ge 5x-1$

$x\ge 5x-2$

$-4x\ge -2$

$4x\le 2$

$x\le \frac{1}{2}$

$\left[\begin{array}{cc}Solution:& x\le \frac{1}{2}\\ Decimal:& x\le 0.5\\ IntervalNotation:& (-\infty ,\frac{1}{2}]\end{array}\right]$
