How does anyone know the answer to this?
katrin2010 [14]
Take the common out of both numerator and denominator and cancel out the terms which are equal.

(8x³ - 2x² - 3x)/(12x²- 9x)

= x(8x² - 2x -3)/3x(4x - 3)

= (8x² - 2x -3)/3(4x - 3)

=(4x-3)(2x+1)/3(4x-3)

= (2x+1)/3

Evaluate 5a^2 + 2b^3 when a=4 and b =-4
Darya [45]
Hello there! How are you today?

5a^2 + 2b^3, solve when a = 4 and b = -4

To solve for this, we must replace "a" with 4, and "b" with -4.

I will set it up;

5(4^2) + 2(-4^3)

Simplify the parenthesis (PEMDAS).

5(16) + 2(-64)

Remove the parenthesis by multiplying them by the numbers to the outside of them.

5 x 16 = 80
2 x -64 = -128

We are now left with:
80 - 128

Simplify.

-48 is your final answer.

I hope this helps!

Calculate dy/dx when xy^3 + y =3x
Yuki888 [10]
The answer is the option D.

You have to use implicit derivative

1) dy / dx = y'

2)

xy^3+y=3x

y^3+3xy^2y'+y'=3

(3xy^2+1)y'=3-y^3

y'= (3-y^3)/(3xy^2+1)

y'=(3-y^3)/(1+3xy^2)
