Hallar las coordenadas de un punto P (x, y) que divida el segmento que determinan P1 (x1,y1) y P2 (x2,y2) en la relación r = P1P / PP2 a) P1 (4,-3), P2 (1,4), r = 2/1
b) P1 (5,3), P2 (-3,-3), r = 1/3
c) P1 (-2,3), P2 (3,-2), r = 2/5
d) P1 (0,3), P2 (7,4), r = - (2/7)
e) P1 (-5,2), P2 (1,4), r = - (5/3)
f) P1 (2,-5), P2 (6,3), r = 3/4

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.

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

24+x=y
