First, let's split the compound inequality into separate inequalities.
Compound Inequality: 8≤ x&+ 2 < 13
First Inequality: 8 ≤ x &+2
Second Inequality: x &+2 < 13
Notice that compound inequalities written in this way are the same as compound inequalities that are connected by the word and.
8≤ x+2 and x+2<13
Let's solve the inequalities separately.
First Inequality
Inequalities can be solved in the same way as equations, by performing inverse operations on both sides until the variable is isolated. The only difference is that when you divide or multiply by a negative number, you must flip the inequality sign.
The solution set to the compound inequality is the intersection of the solution sets.
First Solution Set: 6≤ x&
Second Solution Set: x&< 11
Intersecting Solution Set: 6≤ x& < 11
