Given points (0,0) and (3,6), find the point which partitions the segment into 3: 2.

(1.8, 3.6)
(2,4)
(3,5)
(4.5,9)

! in advance!

Dividing a number by the ratio 3:2 means dividing into 3+2 = 5 parts

Let (0, 0) be (x₁, y₁) and (3, 6) be (x₂, y₂)

Find one part of the share for each axes, we do



Then multiplying the one part back into 3: 2, we have
for the x - axis ⇒ (3×0.6) : (2×0.6) = 1.8: 1.2
for the y - axis ⇒ (3×1.2) : (2×1.2) = 3.6: 2.4

The coordinate that divides the segment into 3 parts and 2 parts is (1.8, 3.6)

Correct A

D. X=-9

Because..

You start out with like terms

3x+3-2x=-6

x+3=-6

Now you move it to the right side and change the sign itself

x=-6-3

Now you get x=-9 as your answer
