Answer:
.
Step-by-step explanation:
Given homogeneous equation
Substitute y=ux , 
Now,
Integrating both side we get
lnu=-2lnx+lnC
Where lnC= integration constant
Cancel ln on both side
Substitute
Then we get
xy=C
.
Answer:.
Answer:
x = 2 ±i
Step-by-step explanation:
x^2 = 4x-5
Subtract 4x from each side
x^2 - 4x = 4x-5 -4x
x^2 - 4x= -5
Complete the square
Take the coefficient of the x term, divide by 2 and square it
-4/2 =2 2^2 =4
Add 4 to each side
x^2 -4x+4 = -5 +4
The left side is (x-coefficient of the x term/2)^2
(x-2)^2 = -1
Take the square root of each side
sqrt((x-2)^2) = sqrt(-1)
x-2 = ±i
Add 2 to each side
x-2+2 = 2 ±i
x = 2 ±i
Answer:25 sales
Step-by-step explanation:
$100 is how much you want to make.
you automatically make $50
100-50=50
if you make $2 per sale then you make the equation 50/2=?
this will give you 25 Sales
