LiRa [457]3 years ago
8 0

Answer:

18x^2 - 9

Step-by-step explanation:

y = f(x)= 6x^3 - 9x + 4

dy/dx = d/dx(6x^3) - d/dx(9x) + d/dx (4)

=6.d/dx(x^3) - 9.d/dx (x) + d/dx. (4)

=6.3x^2 - 9.1 + 0 =18x^2 - 9

Geometry - Will give 5 stars + Thanks!
Fynjy0 [20]

Answer:

<h2>x = 3 and y = 4</h2>

Step-by-step explanation:

We know:

The diagonals in a parallelogram divide by halves.

Therefore KG = UG and DG = CG.

We have

KG = 5y - 8, UG = 3y, DG = 4x - 7, CG = x + 2

Substitute:

5y - 8 = 3y          <em>add 8 to both sides</em>

5y = 3y + 8      <em>subtract 3y from both sides</em>

2y = 8      <em>divide both sides by 2</em>

y = 4

---------------

4x - 7 = x + 2           <em>add 7 to both sides</em>

4x = x + 9            <em>subtract x from both sides</em>

3x = 9     <em>divide both sides by 3</em>

x = 3
