Answer:
[tex]6\,b-9\leq -16[/tex]
Step-by-step explanation:
SInce the sentence reads "Nine subtracted from..." start by creating the quantity that 9 would be subtracted from, to make the expression more obvious. So let's begin by making the product of 6 times a "number" (unknown value) and use for the unknown the letter "b" as requested:
[tex]6\,b[/tex]. Now proceed to subtract 9 from this expression:
[tex]6\,b-9[/tex]
The sentence now continues saying that this expression is at most -16. So we understand that the quantity we created above has to be smaller or at most equal to -16. Therefore, we use the inequality symbol "[tex]\leq[/tex]" to complete the sentence in mathematical terms:
[tex]6\,b-9\leq -16[/tex]
