Answer:
The graph and the number line in the attached figure
Step-by-step explanation:
we have
[tex]-2x+7 < 23[/tex]
Solve for x
subtract 7 both sides
[tex]-2x+7-7 < 23-7[/tex]
[tex]-2x < 16[/tex]
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
[tex]x > -8[/tex]
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)
The graph and the number line in the attached figure


Answer:
Step-by-step explanation:
Find the graph attached below
Given the inequality
-2x + 7 < 23−2x+7<23
Simplifying the inequality
-2x+7-7<23-2x+7-7<23-7
-2x<23-2x<16
Subtracting 23 from all sides
-23x-23<-2x<-7
Dividing through by -2
-23x-23/-2 < x < 7/2
Solving -23x-23/-2< x
x > -23x-23/-2
-2x < -23x-23
-2x+23x <-23
21x<-23
x<-23/21
The solution to the inequality are x<-23/21 and x<7/2
