Answer:
y = (6ln(x) + C)/x
A
is not a solution to the differential equation
x²y' + xy = x²
as required. This is probably due to an error in typing either the differential equation, or the value of y.
When you've checked the correct values, the same procedure is followed in obtaining the desired result.
Step-by-step explanation:
Suppose y = (6ln(x) + C)/x
is a solution to the differential equation
x²y' + xy = x²
Differentiate y with respect to x
y' = (6/x)/x - (6ln(x) + C)/x²
= (6 - 6ln(x) - C)/x²
Using this value in the differential equation,
x²(6 - 6ln(x) - C)/x² + x(6ln(x) + C)/x
= 6 - 6ln(x) - C + 6ln(x) + C
= 6
Answer:I think its the second one
Step-by-step explanation:
Answer:
two solution : 10 ; -4
Step-by-step explanation:
hello :
6x=x²- 40
x²-6x-40 =0
(x-10)(x+4) =0
Hello!
Firstly, let's subtract the one time charge of $100, because we know for sure that Kaya is paying that:
347.50 - 100 = 247.50
Now, divide this by the hourly rate:
247.50 / 45 = 5.5
Kaya rented the limo for 5.5 (five and a half) hours. =)
