<u><em>The complete question in the attached figure</em></u>
Let
h ----> the minimum height h in inches necessary to ride a certain roller coaster
we have
The solution for this inequality is the interval [48,∞)
so
The value of h must be greater than or equal to 48 inches
<u><em>Verify who can ride the roller coaster</em></u>
1) Miguel 42 in
substitute the value of h in the inequality
----> is not true
therefore
Miguel can't ride the roller coaster
2) Patrick 45 in
substitute the value of h in the inequality
----> is not true
therefore
Patrick can't ride the roller coaster
3) Anna 48 in
substitute the value of h in the inequality
----> is true
therefore
Anna can ride the roller coaster
4) Sara 52 in
substitute the value of h in the inequality
----> is true
therefore
Sara can ride the roller coaster
