    Answer:
    S:{−2, −3}
    Step-by-step explanation:
    Determine which integers in the set S: {−2, −3, −4, −5} will make the inequality 2p − 8 < 5p + 4 true.
    S:{−2, −3}
    S:{−3, −4}
    S:{−4, −5}
    S:{−2, −5}
    We will substitute in the integers and find the ones that make the equation true:
    2p − 8 < 5p + 4 when p = -2
    2(-2) − 8 < 5(-2) + 4
    -4 − 8 < -10 + 4
    -12 < -6 TRUE
    ____________________
    2p − 8 < 5p + 4 when p = -3
    2(-3) − 8 < 5(-3) + 4
    -6 − 8 < -15 + 4
    -14 < -11 TRUE
    ____________________
    2p − 8 < 5p + 4 when p = -4
    2(-4) − 8 < 5(-4) + 4
    -8 − 8 < -20 + 4
    -16 < -16 FALSE
    ____________________
    2p − 8 < 5p + 4 when p = -5
    2(-5) − 8 < 5(-5) + 4
    -10 − 8 < -25 + 4
    -18 < -21 FALSE
