On a coordinate plane, a line is drawn from point k to point j. point k is at (9, 2) and point j is at (1, negative 10). what is the x-coordinate of the point that divides the directed line segment from k to j into a ratio of 1: 3? x = (startfraction m over m + n endfraction) (x 2 minus x 1) + x 1 –1 3 7 11

i got 86 for this

hope this !

if you need an explanation just ask

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
