If f(x) = 6x-11, what is f(-6)?
1 answer:
If f(x) = (6x-11), then f(-6) = -47.
We are provided in the question statement with a function "f(x)" whose output is a polynomial of 1 variable and degree 1.
To obtain the value of f(-6) from the output polynomial of the function f(x), we will simply need to substitute (-6) as the value of x in the polynomial and calculate the final value.
So,
Hence, f(-6) = -47.
- Polynomial: In mathematics, an expression of more than two algebraic terms, especially the sum of several terms that contain the same variable(s) of different powers and individual, distinct co-efficients.
- Function: In Mathematics, a function is an operator which on taking input, provides a certain output.

Answer:
The height of one book is
in
Explanation:
We know that the 3 books are of the same size. This means that the 3 books have the same height.
Assume that each book has a height x in
Now, we know that the total height is 10 in.
Therefore:
x + x + x = 10
3x = 10
x = 10/3 in
Based on the above, the height of one book is 10/3 in
Hope this helps :)
