Answer:
up 10
Step-by-step explanation:
The function would change from
C(x) = 0.3x + 40
to
C(x) = 0.3x + 50
The change is only to the y-intercept, so the graph of the function will move up 10.
Answer with Step-by-step explanation:
The given differential equation is
Now the above differential equation can be re-written as
Checking for exactness we should have
As we see that the 2 values are equal thus we conclude that the given differential equation is exact
The solution of exact differential equation is given by
The value of 
can be obtained by differentiating u(x,y) partially with respect to 'y' and equating the result with P(x,y)

Answer:
Step-by-step explanation:
-2(11-12)=-4(1-6x) becomes -2(-1) = -4(1 - 6x)
Next, we divide both sides by -2, obtaining -1 = 2(1 - 6x), and then
-1 = 2 -12x, or
-3 = -12x
Simplifying this result, we get 1 = 4x, or x = 1/4
We conclude that -2(11-12)=-4(1-6x) has ONE solution, which is x = 1/4
