Answer:
b < -10 and (-∞, -10)
Step-by-step explanation:
I won't draw the number line but I will do the interval notation.
Interval notation is a way to describe infinite or finite sets with numbers.
To solve the inequality first add 2 to both sides to get:
-b > 10 Multiply both sides by -1:
b < -10 is the simplification of the inequality .
Now to write this in interval notation you need to know which direction the values are increasing, since b is less than -10, the values are going down starting from -10 (not including -10).
Interval notation: (-∞, -10)

This has an explanation.
We have been given that last year, the business had profit of $8000.
Further, we are given that, the profit for this year will be 5 times as great the profit of last year. So, in order to find profit of current year, we will have to consider 5 times of $8000.
Therefore, we get the profit for current year as:
Therefore, profit for current year would be 40,000 dollars.
The seats are increasing at a rate of four per row. If you were to write this in an equation, it would be y=4X+20, with 4 as the rate of change, 20 as the original amount of seats, and Y as the total number of seats for X rows. Plug in 25 for X and you'll get an answer of 120 seats.
