Answer:
-20.1 degrees Celsius
Step-by-step explanation:
The system started at -12.6 Celsius. It then cooled 7.5 degrees during a reaction. Because it cooled, that means the difference is negative.
-12.6 degrees Celsius - 7.5 degrees Celsius = -20.1 degrees Celsius
It is important to always remember your correct names and variables for numbers in chemistry!
x< -1 is the graph going down or up when x is less than -1? its going down , so this is true
Range is the y values. It appears to go down to y=5 and go up so its not all reals
x< -1 is the graph going down or up when x is less than -1? its going down , so this isn't true
Domain is the x values and it does include all reals
Minimum (-1, 5), is that the value of vertex at the bottom, yes it is, so this is true

There are many types numbers. The set of numbers are defined below.
Complex Numbers: The complex are the addition of real and imaginative numbers. it is represented as a+bi, where a is a real number and b is an imaginary number.
Imaginary Numbers: The imaginary numbers are those numbers which are not real numbers. For example
.
Real Numbers: All numbers in the number system( fractional, roots, positive, negative, decimal, etc) are real numbers. For example 2.1 and 5 etc. Real numbers are categorized in two parts rational and irrational numbers.
1) Irrational numbers: The number which can't expressed in the form of are called irrational numbers. For example
and
etc.
2) Rational numbers: The number which can be expressed in the form of are called irrational numbers. For example 5 and -5.2 etc. It is categorized in two parts fractional and integer numbers.
3)Integer numbers: The rational number which has no decimal value is called integer numbers. For example-8,-2, 0, 5,7 and 100 etc.
4) Whole Numbers: The set of all positive integers including 0 is called known as the set of whole numbers.
5) Natural Numbers: All Whole numbers except 0 are known as natural number.
