    Answer:

    first one, [2.5, 3]

    Step-by-step explanation:

    2a + 3 \geq 8

    2a \geq 8 – 3

    a \geq 5/2

    a \geq 2.5

    if we put a =2 .5 in the equation

    2a +3 \geq 8

    2(2.5) + 3 \geq 8

    5+3 \geq 8

    8 \geq 8

    which is true.

    if we put a = 3 in the equation

    2a + 3 \geq 8

    2(3) +3 \geq 8

    6+3 \geq 8

    9 \geq 8

    which is also true.
