Question

1. for parts (a)-(d), consider the inequality $-13 \leq x - 5$.

a. solve the related equation to find the boundary number.
$-13 = x - 5$
$x = -13 + 5$
$x = -8$

Explanation:

Step1: Set up related equation

$-13 = x - 5$

Step2: Isolate $x$ by adding 5

$x = -13 + 5$

Step3: Calculate the value of $x$

$x = -8$

Answer:

$x=-8$
