Question
Solve the compound inequality
-1 < X - 2 LESS THAN OR EQUAL TO 7
Your problem:
-1 < x - 2 ≤ 7
Add 2 to all three quantities to get x by itself:
-1 + 2 < x - 2 + 2 ≤ 7 + 2
1 < x ≤ 9
Solution set can be expressed this way using interval notation:
(1, 9]
-1<x-2<=7
add 2
1<x<9
area of each layer. i want to know want is a layer.
