I believe it is B, because going down would be negative, and it is subtracting 6.
Answer:
y=x/14+1
Step-by-step explanation:
3(2x-4y) +14-2y=5x
6x-12y+14-2y=5x
6x-14y+14=5x
x+14=14y
x/14+1=y
And dude I feel ur pain no one is responding to my questions :(
Answer:
The number of books produced at which the costs from the two methods be the same is 4668 books
Step-by-step explanation:
Here, we have
For the first production method
Fixed cost = $65,054 and variable cost per book = $8.25
For the second production method
Fixed cost = $12,539 and variable cost per book = $19.50
Therefore, let the number of books at which the to methods cost the same be M, we then have
$65,054 + $8.25 × M = $12,539 + $19.50× M
Which gives
$65,054 - $12,539 = $19.50× M - $8.25 × M
$52515 = $11.25 × M
M = $52515/$11.25 = 4668 books.

PLS STICK YOUR BIG.........
Step-by-step explanation:
Okay, you will need to use the law of cosines for this problem.
The Law of Cosines states (in this case): a^2 = b^2 + c^2 - 2 * b * c * cos A, where "a" is the side opposite angle A (7 inches), and b and c are the other two sides.
Plug the numbers in and you get: 7^2 = 5^2 + 9^2 - 2 * 5 * 9 * cos A, or:
49 = 25 + 81 - 90 * cos A.
Subtract (25 + 81) from both sides to get:
-57 = -90 * cos A.
Divide by -90 on both sides:
cos A = 19/30
To find A, you do the inverse trigonometric function to get:
cos^-1 of (19/30) = A.
I don't have a calculator that can do this right now, but if you plug the left side of the above equation into it (make sure it is in degrees, not radians), you should get A.
