between 8.0 and 8.3 and the temperature at the water
should be between 76°F and 80°F. Let x be the pH
level and y be the temperature. Write and graph
a system of inequalities that describes the proper
pH level and temperature of the water. Compare
this graph with the graph you would obtan if the
temperatures were given in degrees Celsius.
