N-10 because you want to take 10 away from n
** x + 5 = 7
x = 2
** x + 5 = 9
x = 4
{2,4}
Answer:
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.
The solution of your problem is shown on the picture below.
