Answer:

A ( -2 , 9 )

Step-by-step explanation:

<u>Idea:</u> You find the first derivative of f(x), and then set it equal to the desired slope. You'll find some x. That we will use to find the point.

f'(x) = 3x^2 + 12x + 20

f'(x) = 8

3x^2 + 12x + 20 = 8

3x^2 + 12x + 12 = 0

3 ( x^2 + 4x + 4 ) = 0

3 ( x + 2 )^2 = 0

x + 2 = 0

x = -2

So, the desired point is:

A ( -2, f(-2) ) --> A ( -2 , 9 )

Answer: x=65^{\circ}, y=65^{\circ}, z=65^{\circ}

Step-by-step explanation:

All radii of a circle are congruent, so by the base angles theorem

  • z = y = (180-50)/2 = 65.

Also, angles x and y are inscribed in the same arc, and they are thus congruent, meaning x = 65.

Which of the following equations could be used to solve the given equation?
kvasek [131]
Well, lets first start off with combining like terms.

9x + 26 + 7x - 17 = 2x + (-3x) + 5x

9x + 7x + will give you 16x, and 26 - 17 will give you 9. Therefore, the first part of the equation is 16x + 9.

On the other side, you can combine all three terms (2x + 5x - 3x), which will give you 4x.

Using the above steps, you can figure that the answer is 16x +9 = 4x
