Answer:
x= 1÷4
Step-by-step explanation:
2x - 6x + 1 =0
-4x + 1= 0
-4x = -1
Given function is a direct variation
Step-by-step explanation:
The direct proportion is defined as the increase in one quantity causes increase in other quantity.
If y is directly proportional to x, then it is given as:
y = kx
where k is the constant of proportionality
Given
y = 3x
Comparing the general form and given equation we see that both are same where k =3
So,
Given function is a direct variation

Answer:
The answer is x = -2
Step-by-step explanation:
Let
, so that
. Then the ODE becomes linear in
with
Find an integrating factor:
Multiply both sides of the ODE by
:
The left side can be consolidated as a derivative:
Integrate both sides with respect to
to get
where the right side can be computed with a simple substitution. Then
Back-substitute to solve for
.
