If x² + xy – 3y = 3, then at the point (2, 1), dy/dx

Scilla [17]

Answer:

Step-by-step explanation:

We have the equation:

$x^2+xy-3y=3$

Take the derivative of both sides with respect to x:

$\frac{d}{dx}[x^2+xy-3y]=\frac{d}{dx}[3]$

Implicitly differentiate:

$2x+y+x\frac{dy}{dx}-3\frac{dy}{dx}=0$

Solve for dy/dx:

$\frac{dy}{dx}(x-3)=-2x-y\\$

Divide:

$\frac{dy}{dx}=-\frac{2x+y}{x-3}$

To find dy/dx at (2, 1), substitute 2 for x and 1 for y. So:

$\frac{dy}{dx}_{(2, 1)}=-\frac{2(2)+1}{2-3}=-\frac{5}{-1}=5$

Hence, our answer is A.

How would you write 1 17/20 as a percent

Over [174]

1 17/20

the 1 is ur whole number....it stays ur whole number
17/20 = 0.85

so we have 1.85.....to turn it into a percent, move the decimal 2 spaces to the right = 185%

How do you solve these? Please explain steps as well. Thanks.

$7x-3=2x-33 \\
7x-2x=-33+3\\
5x=-30\\
x=-6\\\\
3(x-2)=2(2x-1)\\
3x-6=4x-2\\
4x-3x=-6+2\\
x=-4
