Question

Graph the inequality: a) 4x>18 b) x-8>_24

Answer 1

Step-by-step explanation:

<, > - open circle

≤, ≥ - closed circle

<, ≤ - draw the line to the left

>, ≥ - draw the line to the right

$a)\ 4x>18\qquad\text{divide both sides by 4}\\\\\dfrac{4x}{4}>\dfrac{18}{4}\\\\x>4.5\\\\b)\ x-8\geq24\qquad\text{add 8 to both sides}\\\\x-8+8\geq24+8\\\\x\geq32$
