Question

How do I plot this???

Answer 1

The graph in the attached figure

Explanation:

we have the inequality

`x+2.5 > 7`

Solve for x

Subtract 2.5 both sides

`x+2.5-2.5 > 7-2.5`

`x> 4.5`

The solution is the interval (4.5,∞)

All real numbers greater than 4.5

In a number line the solution is the shaded area at right of x=4.5 (open circle because the number 4.5 is not included)

see the attached figure to better understand the problem
