Answer:
1)10
2)10
3) 7
Step-by-step explanation:
Modulus means we always take the positive value for example
|-3| = +3
1) Find the absolute value of |8 + y| when y = 2
[tex]|8+2| \\|10|\\10[/tex]
2) Find the absolute value of |-8 + y| when y = -2
[tex]|-8+(-2)|\\|-8-2|\\|-10|\\10[/tex]
3) Simplify 4 + |x + 2| when x = -5
[tex]4 + |x + 2|\\4+|-5+2|\\4+|-3|\\4+3\\7[/tex]
Answer:
1. x = ±3
2. x = 13 over 5
3. –4x + 7
