Answer:
The graph and the number line in the attached figure
Step-by-step explanation:
we have
Solve for x
subtract 7 both sides
Divide by -2 both sides
Remember
When you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol
so
The solution is the interval (-8,∞)
All real numbers greater than -8
In a number line the solution is the shaded area at right of x=-8 (open circle)
