Answer:
A monomial can also be a variable, like “m” or “b”. It can also be a combination of these, like 98b or 78xyz. It cannot have a fractional or negative exponent. These are not monomials: 45x+3, 10 - 2a, or 67a - 19b + c.

The ratio of girls to boys would be 16:12 because if you divide 28 by 2 you get 14. subtract 2 to on one of them and add the two to the other. You get 12 and 16. There is a difference of 4 to them and when you add them together you get 28. :)
Its a common technique for remembering the order of operations. The abbreviation pemdas is turned into the phrase "Please excuse my Dear Aunt Sally". It stands for "Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction.
Step-by-step explanation:
"identity" means an operation that does nothing.
For adding numbers, adding 0 changes nothing, so 0 is the identity for addition.
For multiplication, multiplying by 1 changes nothing, so 1 is the identity for multiplication.
If h moves the graph left or right,
![y= \frac{1}{x+h}](https://tex.z-dn.net/?f=y%3D%20%5Cfrac%7B1%7D%7Bx%2Bh%7D%20)
(moves left)
![y= \frac{1}{x-h}](https://tex.z-dn.net/?f=y%3D%20%5Cfrac%7B1%7D%7Bx-h%7D%20)
(moves right)
If a vertical stretch by a factor of |h|, then
![y = \frac{h}{x}](https://tex.z-dn.net/?f=y%20%3D%20%20%5Cfrac%7Bh%7D%7Bx%7D%20)
If h moves the graph up or down,
![y= \frac{1}{x} +h](https://tex.z-dn.net/?f=y%3D%20%5Cfrac%7B1%7D%7Bx%7D%20%2Bh)
(moves up)
![y= \frac{1}{x} -h](https://tex.z-dn.net/?f=y%3D%20%5Cfrac%7B1%7D%7Bx%7D%20-h)
(moves down)
![y= \frac{1}{-hx}](https://tex.z-dn.net/?f=y%3D%20%5Cfrac%7B1%7D%7B-hx%7D%20)
and h = 1
