Answer:

A

Step-by-step explanation:

it can't be any answer with 0, because when you substititue the variable a with 0, it simplifies to 3 ≥ 8 which is false, so C and D are incorrect. it also can't be B since when you substitue a with 1 it simplifies to 6 ≥ 8 which is also false. therefore A is the correct answer, hope this helps :)

Answer:

{2.5, 3}

Step-by-step explanation:

2a + 3 ≥ 8

2a + 3 - 3 ≥ 8 - 3

2a ≥ 5

[tex]\frac{2a}{2}[/tex] ≥ [tex]\frac{5}{2}[/tex]

a ≥ 2.5

From the expression above, a is equal to 2.5 and any number above 2.5

∴The answer is {2.5, 3}
