We know that mid - point of a line segment divides it into two equal parts, that is it divides the segment in the ratio of 1 : 1, so let's find the coordinates of the mid point of line segment joining points (-9 , 3) and (5 , 7).

let the coordinates of the points be x and y, now

  • m = 1

  • n = 1

  • x_2 = 5

  • x_1 =  - 9

  • y_2 = 7

  • y_1 = 3

Using section formula :

value of x :

  • x =  \dfrac{mx_2 - nx_1}{m + n}

  • x =  \dfrac{(1 \times 5) - (1 \times  - 9)}{1 + 1}

  • x =  \dfrac{5 - ( - 9)}{2}

  • x =  \dfrac{5 + 9}{2}

  • x =  \dfrac{14}{2}

  • x = 7

value of y :

  • y =  \dfrac{my_2 -ny_1 }{m+ n}

  • y =  \dfrac{(1 \times 7) - (1 \times 3)}{1 + 1}

  • y =  \dfrac{7 - 3}{2}

  • y =  \dfrac{4}{2}

  • y = 2

So, coordinates of the point which is midpoint of the given line is :

\boxed{ \boxed{ (7, 2)}}

Find the value of n in this equation.
lisabon 2012 [21]

Answer:

  • D. 9

=========================

<h2>Given </h2>

Triangle with:

  • Base of n² -3,
  • Midsegment of 39.

<h2>To find</h2>

  • The value of n.

<h2>Solution</h2>

As per definition of midsegment, it is connecting the midpoints of two sides and its length is half the length of the opposite side of the triangle.

So we have:

  • (n² - 3)/2 = 39

Solve it for n:

  • n² - 3 = 78
  • n² = 81
  • n = √81
  • n = 9

Correct choice is D.

4.8a - 6.3b - 2.1a + 7b
ololo11 [35]
First, you combine like terms. I would start by circling the term and the sign in front of it. (A term is a piece separated by an addition/subtraction sign.) You can only combine terms with the same variable. 4.8a-2.1a-6.3b+7b is the same as your equation, just rearranged. Then, subtract (4.8a-2.1a) which is 2.7a. Add (-6.3b to 7b) The answer is 0.7b. If you have any questions, you can message me!
