Answer :
Final answer:
The numbers that satisfy the inequality are -3 < x < 2.
Explanation:
Let's represent the number as x. The problem states that four times the number, increased by three, is between negative nine and eleven.
We can write this as the compound inequality: -9 < 4x + 3 < 11.
Now, let's solve for x. Subract 3 from all parts of the compound inequality: -9 - 3 < 4x + 3 - 3 < 11 - 3, which simplifies to -12 < 4x < 8.
Finally, divide all parts of the inequality by 4: -12/4 < 4x/4 < 8/4, giving us -3 < x < 2.
So, all the numbers that satisfy this inequality are x such that -3 < x < 2.
