Ill take you up on your proposition: HERES ANOTHER ONE

AC is parallel to OB
-->         -->
AX = 1/4  AB
-->
OA = a
-->
OB = b   and
-->
AC  = m


(a) Express AB in terms of a and b
(b) Express AX in terms of a and b
(c) Express BC in terms of a,b, and m
(d) Given that OX is parallel to BC find the value of m ----------> stuck on this

OB = b   and
-->
AC  = m


(a) Express AB in terms of a and b
(b) Express AX in terms of a and b
(c) Express BC in terms of a,b, and m
(d) Given that OX is parallel to BC find the value of m ----------> stuck on this
a)
OA+AB=OB
AB=b-a
b)
Ax= 1/4(b-a)
c)AB+BC=AC
BC=mb - b + a
d)OX=OA+AX
OX=a + 1/4b - 1/4a
OX= 1/4b + 3/4 a
BC=mb - b + a = m-1(b) + a

therefore, doing the same thing as b4, finding theratio

(1/4)/(m-1)=(3/4)/1
3m/4 - 3/4 = 1/4
3m/4 = 1/4 + 3/4
3m/4 = 1
3m = 4
m=4/3
