Answer:
x ≥ 661.424°F or x[661.424,∞) and x ≤ - 27°F or x(-∞,-27]
Step-by-step explanation:
The melting point of the substance is - 32.78°C, then the melting point in °F is given by
⇒
⇒
⇒ F = - 27.004°F
Again, the boiling point of the substance is 349.68°C, hence, the boiling point in °F is
⇒ F = 661.424°F
Therefore, the range of temperature in °F for which the substance will not be in liquid state will be x ≥ 661.424°F or x[661.424,∞) and x ≤ - 27.004°F or x(-∞,-27.004], where x is the temperature of the substance in °F. (Answer)
Answer:
-2, -3
Step-by-step explanation:
Any 2 negative numbers would work
When 2 negative numbers are multiplied together, the product is always a positive number
Example: -2,-3
(-2)+(-3)=-5
(-2)(-3)=6
The answer is (8/3, -10/3). Hope I helped!
Answer:
A
Step-by-step explanation:
Start with 2x = 12, and end with x = 6.
To do that, you need to divide both sides by 2.
