Matter is in a liquid state when its temperature is between its melting point and its boiling point. Suppose that some substance
has a melting point of - 39.76°C
and a boiling point of 388. 23°C. What is the range of temperatures in degrees Fahrenheit for which this substance is not in a liquid state? (Hint: C F - 32)
(
Express the range as an inequality and in interval notation
Let x represent the temperature in degrees Fahrenheit. What is the range of temperatures for which this substance is not in a liquid state?
(Type an inequality or a compound inequality. Simplify your answer. Use integers or decimals for any numbers in the expression. Round to three decimal places as
needed.)

Answer:
the third selection is corret
Step-by-step explanation:
Ax + by + c = 0, k = - a/b.
so The slope of the first line = ,
the slope of the second line = ;
So these two lines are parallel and they don't intersect
