PLEASE HELP, 50 POINTS<br> QUESTION IS IN THE PICTURE

artcher [175]

Answer:

$-\frac{50}{3}$

Step-by-step explanation:

Find dy/dx of the ellipse $25x^{2} +y^{2}=109$ at (2,3)

Using Implicit Differentiation

Differentiate both sides of the equation with respect to x

$25x^{2} +y^{2}=109$

$50x +2y\frac{dy}{dx}=0$

isolate the term dy/dx

$2y\frac{dy}{dx}=-50x$

$\frac{dy}{dx}=-25\frac{x}{y}$

Evaluate at point (2,3)

For x=2, y=3

$\frac{dy}{dx}=-25(\frac{2}{3})$

$\frac{dy}{dx}=-\frac{50}{3}$

Sovle for x. 2x + 6 = - r - 15

Answer:

$x = \frac{-r - 21}{2}$

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Remember to do the opposite of PEMDAS.

PEMDAS =

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

First, subtract 6 from both sides:

2x + 6 (-6) = -r - 15 (-6)

2x = -r + (-15 - 6)

2x = -r + (-21)

2x = - r - 21

Next, divide 2 from both sides:

$\frac{2x}{2} = \frac{-r - 21}{2}$

$x = \frac{-r - 21}{2}$
