What is the solution to he equation (y/y-4)-(4/y+4)=3^2/y^2-16

kicyunya [14]

Answer:

$y=\pm i \sqrt{7}$

Step-by-step explanation:

Given equation is $\frac{y}{\left(y-4\right)}-\frac{4}{\left(y+4\right)}=\frac{3^2}{(y^2-16)}$

Factor denominators then solve by making denominators equal

$\frac{y}{\left(y-4\right)}-\frac{4}{\left(y+4\right)}=\frac{3^2}{(y^2-16)}$

$\frac{y}{\left(y-4\right)}-\frac{4}{\left(y+4\right)}=\frac{9}{(y+4)\left(y-4\right)}$

$\frac{y\left(y+4\right)-4\left(y-4\right)}{\left(y-4\right)\left(y+4\right)}=\frac{9}{(y+4)\left(y-4\right)}$

$y\left(y+4\right)-4\left(y-4\right)=9$

$y^2+4y-4y+16=9$

$y^2=9-16$

$y^2=-7$

take squar root of both sides

$y=\pm \sqrt{-7}$

$y=\pm i \sqrt{7}$

Hence final answer is $y=\pm i \sqrt{7}$ .

How much does a 5 lb 11 oz roast weigh in grams?

Maurinko [17]

Answer:

2268 grams or 2 kg 268 g

Step-by-step explanation:

<u>How to convert Pounds to Grams</u>

1 pound (lb) is equal to 453.59237 grams (g).

1 lb = 453.59237 g

The mass m in grams (g) is equal to the mass m in pounds (lb) times 453.59237:

m(g) = m(lb) × 453.59237

In this case,

Convert 5 lb to grams:

2267.96 approximately convert to nearest thousands.

m(g) = 5 lb × 453.59237 = 2268 g or 2 kg 268 g
