Olegator [25]

Answer:

  (-1/4)(2x +5y)

Step-by-step explanation:

Multiply and divide by -1/4:

  -\frac{1}{2}x-\frac{5}{4}y=\dfrac{(-\frac{1}{4})(-\frac{1}{2}x-\frac{5}{4}y)}{-\frac{1}{4}}=\left(-\dfrac{1}{4}\right)(-4)\left(-\dfrac{1}{2}x-\dfrac{5}{4}y\right)\\\\=\left(-\dfrac{1}{4}\right)\left(2x+5y)

Y^3-27=9y^2-27y how to factor
Kryger [21]
Hello! And thank you for your question!

First we are going to redo the equation:

<span><span><span>y<span><span>​^3</span><span>​​</span></span></span>−3<span>y^<span><span>​2</span><span>​​</span></span></span>(3)+3(y)×<span>3<span><span>​^2</span><span>​​</span></span></span>−<span>3<span><span>​^3</span><span>​​</span></span></span>=0

Then we are going to use Cube of Difference:

0 = (y - 3)^3

That take cube root of both sides:

0 = y - 3

Finally add 3 to both sides:

3 = y

Final Answer:

y = 3</span></span>
