Find the slope between two points : ( - 5,5 ) and ( 3, - 5 )

vampirchik [111]

(-5,5)(3,-5)
slope = (y2 - y1) / (x2 - x1)
slope = (-5-5) / (3 - (-5)
slope = -10/(3 + 5)
slope = -10/8 = - 5/4 <== ur slope

How do i simplify 2a x 3b x 4c

AlekseyPX

In the expression <span>2a x 3b x 4c,
2, 3 and 4 are the coefficients and a, b and c are the variables.
When such a multiplications is given, multiply the coefficients together and the variables together.

So the product of coefficients = 2</span>×3×4 = 24
the product of variables = a×b×c = abc

Finally multiply the product of coefficients and product of variables.
Final product = 24×abc = 24abc

So <u>24abc</u> is the answer.

Could someone explain this to me?

Ilya [14]

This is a simple differentiation problem. Let's start by taking the derivative of both sides (with respect to x):
$5y^4\frac{dy}{dx}+6y^2x+6x^2y\frac{dy}{dx}+20x^3 = 0$

Simplify:
$\frac{dy}{dx} (5y^4+6x^2y) + 6y^2x+20x^3 = 0$

Solve for dy/dx:
$\frac{dy}{dx} = \frac{-6y^2x-20x^3}{5y^4+6x^2y}$

Now, plug in the given points:
$\frac{dy}{dx} = \frac{-6(2)^2(-1)-20(-1)^3}{5(2)^4+6(-1)^2(2)} = \frac{24+20}{80+12}$

Further simplification gives:
$\frac{dy}{dx}|_{(2,-1)} =\frac{44}{92} = \frac{11}{23}$

So, your answer is 11/23 or B.
