Choose the correct description of the graph of the compound inequality x − 3 < −9 or x + 5 greater than or equal to 10.

Verified Answer :

x - 3 < 9    or    x + 5 ≥ 10
  + 3 + 3               - 5   - 5
     x < 12      or      x ≥ 5

Solution Set: {x|x < 12 or x ≥ 5}, (-∞, 12) or (5, ∞)

Answer:

A number line with an open circle on -6, shading to the left, and a closed circle on 5, shading to the right.

Step-by-step explanation:

The given compound inequality is

\(x-3<-9\) or \(x+5\geq 10\)

We need to find the description of the graph of the compound inequality.

Solve each inequality.

\(x-3<-9\)

Add 3 on both sides.

\(x-3+3<-9+3\)

\(x<-6\)

The value of x is less that -6. Since -6 is not included in the solution set, therefore there is an open bracket at -6.

\(x+5\geq 10\)

Subtract 5 from both sides.

\(x+5-5\geq 10-5\)

\(x\geq 5\)

The value of x is greater than of equal to 5. Since 5 is included in the solution set, therefore there is a closed bracket at 5.

The solution of given compound inequality.

\((-\infty,-6)\cup [5,\infty)\)

A number line with an open circle on -6, shading to the left, and a closed circle on 5, shading to the right.
