Answer:
[ 2, ∞)
Step-by-step explanation:
Given inequality,
[tex]9\leq 17-4x[/tex]
Adding 4x on the both sides of inequality ( by the additive property of inequality )
[tex]9 + 4x \leq 17[/tex]
Subtract both sides by 9 ( by subtraction property of inequality ),
[tex]4x\leq 8[/tex]
Since, 4 > 0, thus, after dividing both sides of inequality the sign will not change,
[tex]x\leq 2[/tex]
⇒ x ∈ [ 2, ∞)
