How could you graph an inequality like this x> 3?

  see below

Step-by-step explanation:

The graph of it on a number line is an open circle at x=3 with a line extending to the right through larger numbers.

When the inequality does not include the "or equal to" case, the boundary is graphed as a dashed line (on an x-y plane) or open circle (on a number line). The shaded area covers values of the variable that meet the condition of the inequality. Here, those are values of x that are more than 3.

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0

the answer is 1030 it's very simple math.
