She would have 106 copies left.I think this because since she has to make 47 copies and since they are double sided you would have to multiply be 2.Which would give you 94 and then you subtract 94 from 200.It would give you 106 in the end.
Answer:

Step-by-step explanation:
Given:
The implicit equation is given as:

In implicit differentiation, we treat 'y' as a function of 'x' and differentiate both sides of the equation with respect to 'x' and then collect all the
together and finally solve for
.
So, differentiating both sides of the above equation with respect to 'x'. This gives,

Therefore, the derivative
implicitly is:

Answer:

Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or
Let
x -----> the amount of weight
y ----- the amount a spring will stretch
we know that
For x=80 lb, y=2.1 in
<em>Find the value of k (constant of proportionality)</em>

substitute the values

The linear equation is

How far will it stretch when 40 pounds is attached?
For x=40 lb
substitute the value of x in the linear equation and solve for y

Do you have a picture I can’t see it my guy
the sum of supplementary angles is 180 degree
therefore
x +2x = 180°
3x = 180
X = 180/3 = 60°
the value of X is 60°
