Question

if p(9x-2,-y) divides the line segmentjoining A(3x+1,-3) and B (8x,5) in the ratio 3:1 .find the values os x and y​

Answer 1

Answer:

given: x¹=3x+1

y¹=-3

x=9x-2

y=-y

x²=8x

y²=5

m¹=3

m²=1

solution:

Step-by-step explanation:

x=(m¹x²+m²x¹)/m¹+m² 9x-2 =(3*8x+1*3x+1)/3+4

9x-2=(24x+3x+1)/7

18x-14=27x+1

-14-1=27x-18x

-15=10x

x=-3/2

y=m¹y²+m²y¹/m¹+m²

-y=(3*5+1*-3)/3+4

-y=(15-3)/7

-7y=12

y=-12/7
