Can Someone Can Help Me Solve This Inequality class=

Sagot :

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)
