Answer:
[tex]8x+9<4[/tex] and [tex]8x+9>-4[/tex].
Step-by-step explanation:
The given inequality is
[tex]|8x+9|<4[/tex]
We need to rewrite the given inequality as two linear inequalities.
We know that |8x+9|>0 but (8x+9) can be positive or negative.
For [tex]|8x+9|<4[/tex], the value of (8x+9) must be lies between -4 and 4.
i.e., [tex]-4<8x+9<4[/tex]
If 8x+9 positive, then
[tex]8x+9<4[/tex] ...(1)
If 8x+9 negative, then
[tex]8x+9>-4[/tex] ...(2)
Therefore, the two inequalities are [tex]8x+9<4[/tex] and [tex]8x+9>-4[/tex].
