Solve -2a-5> 3. which graph shows the solutions?

The solution to the inequality is -2a-5>3 is a < -4

The graph that represents the solution has been attached

The given inequality is:

-2a   -  5   >    3

Add 5 to both sides of the inequality

-2a  -  5  +  5  >   3  +  5

-2a     >    8

Divide both sides by 2

Multiply both sides by -1 and change the inequality sign from > to <

-1(-a)   <  -1(4)

a    <   -4

The graph that shows the solution of the inequality is attached below

Step-by-step explanation:

Given

- 2a - 5 > 3 ( add 5 to both sides )

- 2a > 8

Divide both sides by - 2, reversing the direction of the inequality sign as a consequence of dividing by a negative quantity

a < - 4

Since a is less than we require an open circle at - 4 on the number line.

Since less than the arrow head is pointing to the left, that is
