Step-by-step explanation:
Inequalities of the form | x | < a , always have solutions of the form
- a < x < a
Given | x - 12 | < 3, then
- 3 < x - 12 < 3 ( add 12 to all 3 intervals )
9 < x < 15
x−12<3
Step 1: Add 12 to both sides.
x−12+12<3+12
x<15
f(x)=20+0.06x
y= -2/7x +4
Answer:C
12/4+13=16 2+22/4=7.5
you answer is the last option im 100 percent sure.
