Question

1. Find the co-ordinates of the point which divides the join of (3,-4) and (-5,-3) externally in the ratio 3:4.

Answer 1

Answer:

.p(x,y)=p(3/7,-23/7)

Step-by-step explanation:

Let p be the co-ordinate of the point

A(3,-4),b(-5,-3)

m:n=3:4

p(x)=mx2+nx1/m+n

p(x)=3*-5+4*3/3+4

p(x)=-15+12/7

p(x)=-3/7

p(y)=my2+ny1/m+n

p(y)=3*-3+4*-4/3+4

p(y)=-9-16/7

p(y)=-23/7

p(x,y)=p(3/7,-23/7)

Hope this helped!!
