Answer:
(−∞, 2)∪(2, ∞)
Step-by-step explanation:
Domain is all the values that "x" can be
since finding all the values which "x" can be is too hard we will find out the values which "x" can't be- this means equating the denominator to "0" so that the function will be undetermined:

since we need the denominator to be "0" we must use the opposite of (-2) which is "2" so we will substitute "2" in the place of "x"
- the function is now "undetermined" since nothing can be divided by 0 we need to write our answer in proper domain/range format

Answer:

Step-by-step explanation:
It's given in the question that;
The spinner is divided into 11 equal sections from 0 to 10.
You spin the spinner <u>ONCE!</u><u> </u>
The total number of possibilities is six, and the total number of sample spaces is 11.
So the probability of getting an even number is;

Answer:
The weight of each circle is 2g
Hello!
To solve this you have to find the ratio between the two cylinders
Cylinder 1 height is 30
Cylinder 2 height is 20
this is a 30:20 ratio
This can be reduced to a 3:2 ratio
Now you look for one that are also equal to 3:2
3 * 7 = 21
2 * 7 = 14
The answers are 3:2 and 21:14
Hope this helps!
