Respuesta :

Answer:

first one, [2.5, 3]

Step-by-step explanation:

2a + 3 [tex]\geq[/tex] 8

2a [tex]\geq[/tex] 8 - 3

a [tex]\geq[/tex] 5/2

a [tex]\geq[/tex] 2.5

if we put a =2 .5 in the equation

2a +3 [tex]\geq[/tex] 8

2(2.5) + 3 [tex]\geq[/tex] 8

5+3 [tex]\geq[/tex] 8

8 [tex]\geq[/tex] 8

which is true.

if we put a = 3 in the equation

2a + 3 [tex]\geq[/tex] 8

2(3) +3 [tex]\geq[/tex] 8

6+3 [tex]\geq[/tex] 8

9 [tex]\geq[/tex] 8

which is also true.
The first one: {2.5,3}
