Answer:
The range of heights of the cheerleaders is the interval [58, 74)
All real numbers greater than or equal to 58 inches and less than 74 inches
Step-by-step explanation:
we have
[tex]260 \leq 4h+28 <324[/tex]
Divide the compound inequality into two inequalities
[tex]260 \leq 4h+28[/tex] -----> inequality A
[tex]4h+28 <324[/tex] -----> inequality B
Solve inequality A
[tex]260 \leq 4h+28[/tex]
Subtract 28 both sides
[tex]232 \leq 4h[/tex]
Divide by 4 both sides
[tex]58 \leq h[/tex]
Rewrite
[tex]h \geq 58\ in[/tex]
Solve the inequality B
[tex]4h+28 <324[/tex]
Subtract 28 both sides
[tex]4h <296[/tex]
Divide by 4 both sides
[tex]h <74\ in[/tex]
therefore
The range of heights of the cheerleaders is the interval [58, 74)
All real numbers greater than or equal to 58 inches and less than 74 inches
