The answer is: 5/4 ; or, write as: 1¼ ; or, write as: 1.25 .
__________________________________________________
Explanation:
_______________
Method 1)
______________________________
5/8 * 2 = 5/8 * 2/1 = (5*2)/(8*1) = 10/8 = (10÷2)/(8÷2) = 5/4 = 1¼ = 1.25 .
_______________________________
Method 2).
______________________________
5/8 * 2 = 5/8 + 5/8 = (5+5)/8 = 10/8 = (10÷2)/(8÷2) = 5/4 = 1¼ = 1.25 .
________________________________________________________
Method 3)
________________________________________________________
5/8 * 2 = 5/8 * 2/1 ; The "8" cancels to a "4" ; and the "2" ; cancels to a "1" ;
since: "8÷2=4" ; and since "2÷2=1" ;
________________________________________________
So; we rewrite as: 5/4 * 1/1 = 5/4 * 1 = 5/4 = 1¼ = 1.25 .
_______________________________________________
Method 4)
_______________________________________________
5/8 * 2 = (5÷8) * 2 = 0.625 * 2 = 1.25
_______________________________________________

If xy + y² = 6, then the value of dy/dx at x= -1 is

mylen [45]

Hi there!

$\large\boxed{\text{At (-1, -2), }\frac{dy}{dx} = -\frac{2}{5}}}$

$\large\boxed{\text{At (-1, 3), }\frac{dy}{dx} = -\frac{3}{5}}}$

We can calculate dy/dx using implicit differentiation:

xy + y² = 6

Differentiate both sides. Remember to use the Product Rule for the "xy" term:

(1)y + x(dy/dx) + 2y(dy/dx) = 0

Move y to the opposite side:

x(dy/dx) + 2y(dy/dx) = -y

Factor out dy/dx:

dy/dx(x + 2y) = -y

Divide both sides by x + 2y:

dy/dx = -y/x + 2y

We need both x and y to find dy/dx, so plug in the given value of x into the original equation:

-1(y) + y² = 6

-y + y² = 6

y² - y - 6 = 0

(y - 3)(y + 2) = 0

Thus, y = -2 and 3.

We can calculate dy/dx at each point:

At y = -2: dy/dx = -(-2) / -1+ 2(-2) = -2/5.

At y = 3: dy/dx = -(3) / -1 + 2(3) = -3/5.

Find the quotient of -85^2-27n+76 / -17n-19

bagirrra123 [75]

Answer:
5n-4

Explanation:
The given expression is:
$\frac{-85n^2-27n+76}{-17n-19}$

1- Take the negative as a common factor from both the numerator and the denominator. This will give us:
$\frac{-(85n^2+27n-76)}{-(17n+19)}$

2- Cancel out the negative sign (common factor) from the numerator and denominator. This will give us:
$\frac{(85n^2+27n-76)}{(17n+19)}$

3- Factor the numerator. This wil give:
$\frac{(5n-4)(17n+19)}{(17n+19)}$

4- Finally, cancel out the (17n+19) which common in both numerator and denominator. This will give us the final expression:
5n-4

Hope this helps :)
