Which expressions are equivalent to z + (z + 6) z+(z+6)z, plus, left parenthesis, z, plus, 6, right parenthesis ?
Scorpion4ik [409]

In the question, the given expression is

z+(z+6)

And we have to find the equivalent expression to the given expression .

First we remove the parenthesis

z+z+6

Now we combine the like terms, and here like terms are z and z, therefore on combining , we will get

z+z+6 = 2z+6

And that's the required equivalent expression .

Consider the differential equation 4y'' â 4y' + y = 0; ex/2, xex/2. Verify that the functions ex/2 and xex/2 form a fundamental
Kazeer [188]

Check the Wronskian determinant:

W(e^{x/2},xe^{x/2})=\begin{vmatrix}e^{x/2}&xe^{x/2}\\\frac12e^{x/2}&\left(1+\frac x2\right)e^{x/2}\end{vmatrix}=\left(1+\frac x2\right)e^x-\frac x2e^x=e^x\neq0

The determinant is not zero, so the solutions are indeed linearly independent.

Okay can you please help me do this
sertanlavr [38]

Answer:

y=3

Step-by-step explanation:

Multiply 9 from both sides to cancel it out.

-27=-y/9

/9      /9

-3=-y

We can't have a negative variable, so we divide -1 from both sides.

-3=-y

/-1  /-1\

3=y
