The solution to the mechanism is the pair (9, 6)

**Step-by-step explanation:**

Hi!

First, let´s write the device of equations:

-y² + 6y + x -9 = 0

6y = x +27

The services of the mechanism are the bag (x, y) that accomplish both equations.

Let´s take the second equation and also solve it because that x:

6y = x +27

Subtract 27 indigenous both political parties of the equation

6y - 27 = x

Now, we deserve to replace x in the very first equation and solve it because that y:

-y² + 6y + x -9 = 0

-y² + 6y + 6y - 27 -9 = 0

-y² + 12y - 36 = 0

Notice the -y² + 12y - 36 = -(y - 6)², then:

-(y - 6)² = 0

y - 6 = 0

y = 6

(alternatively you can solve the quadratic equation using the quadratic formula).

Now let´s find the worth of x:

x = 6y -27

x = 6·6 -27

x = 9

The solution to the mechanism is the pair (9, 6)

Please view the attached figure. The allude where the curves intersect is the equipment to the system.

What is the y-intercept of the line whose equation is y=-x-2?

dalvyx <7>

**medtox.org:**

-2

**Step-by-step explanation:**

If we have actually an equation that the kind y = mx +b then the y-intercept is b.

So now right here we have actually y =-x - 2. Thus b = -2 and we conclude the y-intercept is -2.

What is the loved one maximum value of the role f(x) = –x3 + 6x2 – 9x – 1?

Vlad <161>

**medtox.org:**

** -1.**

**Step-by-step explanation:**

First find the derivative the f(x):

f\"(x) = -3x^2 + 12x - 9 = 0 for a best or minimum.

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

(x - 1)(x - 3) = 0

x = 1, 3.

To uncover which offers a family member maximum we discover the 2nd derivative:

f\"(x) = -6x + 12

When x = 1 f\"(x) = 6, positive.

when x = 3, f\"(x) = -6, negative.

So** x = 3 **gives a **maximum value of f(x).See more: Moises Y Los Diez Mandamientos Capitulo 157, Moisés Y Los Diez Mandamientos Capítulo 157**

f(3) = -(3)^3 + 6*(3)^2 - 9(3) - 1 =** -1 ** (medtox.org).
