Mathematics
1 answer:
Verdich [7]3 years ago

Answer:

  (3, 3) and (15, 15)

Step-by-step explanation:

The points equidistant from the given point and the y-axis lie on the parabola that has (3,6) as its focus and the y-axis as its directrix. The equation for that can be simplified from ...

  (x -3)^2 +(y -6)^2 = x^2

  -6x +9 +y^2 -12y +36 = 0 . . . . . subtract x^2, eliminate parentheses

We can find the points that lie on the line y=x (equidistant from both axes) by substituting y for x or vice versa. Then we have the quadratic ...

  x^2 -18x +45 = 0 . . . . substitute x for y and collect terms

  (x -3)(x -15) = 0 . . . . factor it

  x = 3 or 15

So, the points of interest are (x, y) = (3, 3) and (x, y) = (15, 15).

Help please! Will give brainly!!! Which of the following equations have the same solution? Give reasons for your answer that do
djyliett [7]

Answer:

a and f

Step-by-step explanation:

a. x + 3 = 5x - 4

x - 5x = -4 - 3

-4x = -7

x = -7/-4

x = 7/4

b. x - 3 = 5x + 4

x - 5x = 4 - 3

-4x = 1

x = -1/4

c. 2x + 8 = 5x - 3

2x - 5x = -3 - 8

-3x = -11

x = -11/-3

x = 11/3

d. 10x + 6 = 2x - 8

10x - 2x = -8 - 6

8x = -14

x = -14/8

e. 10x - 8 = 2x + 6

10x - 2x = 6 + 8

8x = 14

x = 14/8

f. 0.3 + x/10 = 1/2x - 0.4

3/10 + x/10 = 1/2x - 4/10

x/10 - 1/2x = -3/10 - 4/10

x/10 - 5/10x = -7/10

-4x/10 = -7/10

-4x = -7

x = -7/-4

x = 7/4

What is the distance, to the nearest whole number, from K (5, 6) to P (1, 1)?
Elza [17]

Answer:

<h3>The answer is 6 units</h3>

Step-by-step explanation:

The distance between two points can be found by using the formula

d =  \sqrt{ ({x1 - x2})^{2}  +  ({y1 - y2})^{2} }  \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

K (5, 6) P (1, 1)

The distance from K to P is

|KP|  =  \sqrt{ ({5 - 1})^{2} +  ({6 - 1})^{2}  }  \\  =  \sqrt{ {4}^{2} +  {5}^{2}  }  \\  =  \sqrt{16 + 25}  \\  =  \sqrt{41}  \\  = 6.403124

We have the final answer as

<h3>6 units to the nearest whole number</h3>

Hope this helps you
