In 1958, NASA began its search for astronauts
for project Mercury, the first man-in-space program.
The initial qualifications for astronaut candidates
specified males between 25 and 40 years of age, who were at
least 5-foot, 4 inches tall but no taller than 5 foot,
11-inches. Write and graph a system of
inequalities that represent the range of heights and ages
for qualifying astronauts.
