What are the x- and y- coordinates of point P on the directed line segment from K to J such that P is 3/5 the length of the line
const2013 [10]

Answer:

option A)

(40, 96)

Step-by-step explanation:

Given that,

The coordinates of point K and J are

K(160,120)

J(-40,80)

x1 = 160

x2 = -40

y1 = 120

y2 = 80

P is (3/5) the line of the line segment from K to J

So, KP = (3/5) KJ   and  JP = (2/5) KJ

OR we will divide the length of KJ with the ratio 3 : 2 from K

m : n

3 : 2

m = 3

n = 2

by using this formula and putting values in it

xp = (m/m+n)(x2-x1) +  x1

yp = (m/m+n)(y2-y1) +  y1

xp = (3/3+2) (-40-160) +  160

yp = (3/3+2) (80-120) +  120

xp = 40

yp = 96

The difference of 3 times a number and 10 is 122.
Natalija [7]

Answer:

Let x = the 2nd number

Let x + 8 = the first number

Let 4x = the third number

x + x + 8 + 4x = 122

6x + 8 = 122

6x = 114

x = 19

x + 8 = 19 + 8 = 27

4x = 4(19) = 76

Step-by-step explanation:

The sum of three numbers is 122 . The first number is 8 more than the second. The third number is 4 times the second
