Question

17 solve the inequality. (a) (x + 8geq18) (b) graph the inequality.

Explanation:

Step1: Isolate the variable x

Subtract 8 from both sides of $x + 8\geq18$.
$x+8 - 8\geq18 - 8$

Step2: Simplify the inequality

$x\geq10$

Step3: Graph the inequality

For $x\geq10$, we use a closed - circle at 10 (since x can equal 10) and draw an arrow to the right to represent all values of x that are greater than or equal to 10.

Answer:

(a) $x\geq10$
(b) On the number - line, place a closed circle at $10$ (because the inequality is $\geq$) and draw an arrow to the right.
