Answer:

\dfrac{dy}{dx}=-\dfrac{2x-y-1}{2y-x-1}

Step-by-step explanation:

Differentiating, you get ...

... x·dy +y·dx +dx +dy = 2x·dx +2y·dy

Collecting terms gives ...

... dy(x +1 -2y) = dx(2x -y -1)

... dy/dx = -(2x -y -1)/(2y -x -1)

Is 50 a perfect square ? Explain your answer please 
xeze [42]
No, 50 is not a perfect square.  A perfect square is any number that can be divided by any number to get the quotient as the same number AND the quotient must be rational.  When you divide 50 so that the quotient equals the divisor, you will get an irrational number.  Therefore, 50 is not a perfect square.

What is the average of 132 and 1/2 137 and 2/3
tino4ka555 [31]
If you would like to find the average of 132 1/2 and 137 2/3, you can calculate this using the following steps:

<span>132 1/2 = 265/2
137 2/3 = 413/3
</span>
132 1/2 + 137 2/3 = 265/2 + 413/3 = 795/6 + 826/6 = 1621/6
<span>1621/6 / 2 = 1621/12 = 135 1/12
</span>
The correct result would be <span>135 1/12.</span>

Mystery number: The number is less than 190000 and greater than 180000.
Kipish [7]
The answer to it is    
180, 000 <n> 190, 000 
180,000 + 2000 = n = 5000-187, 000 
182,000 = n = 182, 000   
Or,  
 180, 000 <n> 190,000                     
 n + 5000= 187, 000                           n – 2000 = 180, 000 
 n= 187, 000- 5000                             n = 180, 000 + 2000 
 n= 182, 000                                       n= 182, 000
