0.5y/4/9=y+3/8
PIT_PIT [208]

Step-by-step explanation:

The question needs to be more specific. But assuming it is 0.5y/(4/9), I will solve it.

This would make it 4.5y/4 =y + 3/8

- Multiply 4 to both sides

4.5y = 4y + 12/8

- Subtract 4y to both sides

0.5y = 12/8

- Divide both sides by 0.5

y = 3

Now plug in to check.

0.5(3)/(4/9)=3+3/8

Both equals 3.375!

If this helped, please feel free to pick this answer as the brainliest! Thank you very much and have a wonderful day!

Find the possible values of k if one of the roots of the quadratic equation x^2 - kx + 8 = 0 is twice the other.​
kondor19780726 [428]

Answer:

k=\pm 6

Step-by-step explanation:

The given quadratic equation is :

x^2 - kx + 8 = 0

One of the roots of this equation is twice that of the other. Let the roots are \alpha \ and\ \beta, \alpha =2\beta

Sum of roots, \alpha +\beta =\dfrac{-b}{a}

\alpha +\beta =\dfrac{-(-k)}{1}\\\\\alpha +\beta =k\\\\3\beta =k\ .......(1)

Product of roots,

\alpha \beta =\dfrac{c}{a}\\\\2\beta ^2=\dfrac{8}{1}\\\\\beta =\pm 2

If \beta =\pm2,

k=3(2)\\\\=\pm 6

So, the value of k is equal to \pm 6.
