Point D is 1/n of the way from C(−2.5, 1.25) to E(5, 15). What are the coordinates of D if n = 5?
prisoha [69]

The coordinate of point D will be ( -0.5, 0.25 ).

<h3>What is coordinate geometry?</h3>

A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.

Given that point, D is 1/n of the way from C(−2.5, 1.25) to E(5, 15), and the value of n = 5.

The coordinates of point D will be:-

D = ( 1 / n ) C

D = ( 1 / n ) ( -2.5 , 1.25 )

D = ( 1 / 5 ) ( -2.5 , 1.25 )

D = ( -0.5 , 0.25 )

Therefore, the coordinate of point D will be ( -0.5, 0.25 ).

Answer:

20x+21y+14

Step-by-step explanation:

Combine like terms:

150x-80y+50-50x-25y+20=

100x-80y+50-25y+20=

100x-105y+50+20=

100x-105y+70

100x-105y+70 can be divided by 5 and get 20x+21y+14.

How do you divide 3/8 by 6/7 in simplest form
Ipatiy [6.2K]

Answer:

7/16

Step-by-step explanation:

First, it is good to know that when you divide fractions, you are <em>multiplying it's reciprocal</em>.

<em>6/7's reciprocal is 7/6, since the reciprocal is \frac{1}{6/7}</em>

3/8 / 6/7 =

<u>3/8 * 7/6</u>

Now that we have that, we can just multiply the two:

3/8 * 7/6 =

21/48 =

<u>7/16</u>

Hope this helped :)
