d = b - 3 / 10

Step-by-step explanation:

b = 10d + 3

  • Place +3 in the other side of the equal sign
  • + 3 becomes - 3
  • b - 3 = 10
  • Divide both sides by 10 to make d the subject
  • b - 3 / 10 = 10d / 10
  • d = b - 3 / 10

With the ratio at 1:1, Point C appears to be the midpoint. Use the midpoint formula to ascertain (make sure of) whether Point C
Mila [183]

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete because the coordinates of A, B and C were not given in the question.

However, the following explanation will guide you...

The midpoints, C of two point A and B is calculated as:

C(x,y) = (\frac{x_1 + y_1}{2}, \frac{y_1 + y_2}{2})

Where (x_1, y_1) are the coordinates of A

and

(x_2,y_2) are the coordinates of B

Take for instance, the given coordinates are

A(4,6); B(2,4) and C(3,5)

Then;

Plug in these values in the given formula:

C(x,y) = (\frac{x_1 + y_1}{2}, \frac{y_1 + y_2}{2})

(3,5) = (\frac{4 + 2}{2}, \frac{6 + 4}{2})

(3,5) = (\frac{6}{2}, \frac{10}{2})

(3,5) = (3,5)

In that case,

C is really the midpoint

To the b part: <em>Explaining why ratio 1:1 is used</em>

The reason is that both parts of the ratio are in equal proportion (1 and 1);

Because of this equal proportion, ration 1:1 is right to calculate the midpoint

Write an equation for a rational function with: vertical asymptotes at x = 2 and x = -5 x-intercepts (-1,0) and (1,0) horizontal
solong [7]

Given vertical asymptotes x = 2 and x = -5 .

Therefore Factors of denominator (x-2)(x+5).

x-intercepts (-1,0) and (1,0) .

Therefore factors of (x+1)(x-1).

So far we got rational function = \frac{(x+1)(x-1)}{(x-2)(x+5)}.

Now, we are given horizontal asymptote at y = 9.

Multiplying above express by 9 on the top, we get

f(x)=\frac{9(x+1)(x-1)}{(x-2)(x+5)}.

<h3>Therefore, required rational function is f(x)=\frac{9(x+1)(x-1)}{(x-2)(x+5)}.</h3>
