The expression that represents the cost of y books is 12y + 3.
Given that,
- The charge for the first copy of the book is $15.
- For each extra copy, the charge is $12.
- Here we assume the number of books be y.
Now based on the above information, the expression should be
= 12y + (15 - 12)
= 12y + 3
Therefore we can conclude that option F is correct.

Y = 8(49) + 9(7) + 11
y = 466
Your slope is -2 over -6 which is -1/-3
The vectors are linearly independent if and only if k ≠ -11
<h3>How to solve the vector</h3>
In mathematics, the definition of a vector is a quantity that is made up of both magnitude and also have direction. This type of quantity is not one that is considered based on its position. A very good example of such a quantity with magnitude and direction is acceleration.
Vectors are used to represent items such as position, velocity, physical quantities and others in mathematics and in physics.
In this question,
We have 2v - 3w
We have to multiply 2 by the values of v and multiply 3 with the values of w
this would produce
[2,6,8]-[6,6,12]
subtract w from v
= [-4, 0, -4]
We u as -1, 0 and 10+k
It is not possible to -1 = 10 + k
-11 = k
Hence we have to conclude that they are linearly independent if and only if k ≠ -11
