Answer:
19-12=7, so 4-7=-3, so b is equal to 19
Answer:

Step-by-step explanation:
A way to find the inverse function is to swap the x and y (f(x)) in the equation.

We can check that it is an inverse function by using a property of inverse functions:

If we plug in the f(x) function into the variable x of the inverse function, we should end up with x

It checks out!

Answer:
is a polynomial of type binomial and has a degree 6.
Step-by-step explanation:
Given the polynomial expression

Group like terms

Add similar elements: -8c-8c-9c=-25c

Thus, the polynomial is in two variables and contains two, unlike terms. Therefore, it is a 'binomial' with two, unlike terms.
Each term has a degree equal to the sum of the exponents on the variables.
The degree of the polynomial is the greatest of those.
25c has a degree 1
has a degree 6. (adding the exponents of two variables 'c' and 'd').
Thus,
is a polynomial of type binomial and has a degree 6.
Because if it is a decrease in change, it will be told as a "fall" in change ;')
