a > 0

see graph below

Step-by-step explanation:

The first thing is to solve the inequality:

-5( 1 - 4a) > - 5

expand the parenthesis:

-5(1) -5(-4a) > - 5

-5 + 20a > - 5

collect like terms by adding 5 to both sides:

20a > - 5 + 5

20a > 0

a > 0/20

a > 0

plotting the graph:

5) 0 < 2n + 3n 2 -3 -2 OL2 ntan =oL 50 colin) L=0 3o2n 7) 7-example-1
