    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

    |8+2| \\|10|\\10

    2) Find the absolute value of |-8 + y| when y = -2

    |-8+(-2)|\\|-8-2|\\|-10|\\10

    3) Simplify 4 + |x + 2| when x = -5

    4 + |x + 2|\\4+|-5+2|\\4+|-3|\\4+3\\7
