Answer:

x=-24 & x=4.

Step-by-step explanation:

-5/6x=20

x=20/(-5/6)

x=(20/1)(-6/5)=-120/5=-24

-------------------------------------

2/3(x-7)=-2

2/3x-14/3=-2

2/3x=-2+14/3

2/3x=-6/3+14/3

2/3x=8/3

x=(8/3)/(2/3)

x=(8/3)(3/2)=8/2=4

Find the point, M, that divides segment AB into a ratio of 5:2 if A is at (1, 2) and B is at (8, 16).
d1i1m1o1n [39]
Since M divides segment AB into a ratio of 5:2, we can say that M is 5/(5+2) of the length of AB. Therefore 5/7 × AB.
distance of AB = d
5/7×(x2 - x1) for the x and 5/7×(y2 - y1) for the y
5/7×(8 - 1) = 5/7 (7) = 5 for the x
and 5/7×(16 - 2) = 5/7 (14) = 10 for the y
But remember the line AB starts at A (1, 2),
so add 1 to the x: 5+1 = 6
and add 2 to the y: 10+2 = 12
Therefore the point M lies exactly at...
A) (6, 12)
