The coordinates of the point that divides the line segment directed

from A to B in the ratio of 1 : 2 are ( 6\frac{2}{3} , 4)

Step-by-step explanation:

If point (x , y) divides a line segment whose endpoints are (x_{1},y_{1})

and (x_{2},y_{2}) at ratio m_{1}:m_{2} from (x_{1},y_{1}) , then

  • x=\frac{x_{1}m_{2}+x_{2}m_{1}}{m_{1}+m_{2}}
  • y=\frac{y_{1}m_{2}+y_{2}m_{1}}{m_{1}+m_{2}}

∵ Line segment AB has endpoints A(9 , 3) and B(2 , 6)

∵ Point (x , y) divides the line segment from A to B in the ratio of 1 : 2

∴ x_{1} = 9 and y_{1} = 3

∴ x_{2} = 2 and y_{2} = 6

∴ m_{1}:m_{2} = 1 : 2

Substitute these values in the rules above to find x and y

∴ x=\frac{(9)(2)+(2)(1)}{1+2}

∴ x=\frac{18+2}{3}

∴ x=\frac{20}{3}

∴ x = 6\frac{2}{3}

∴ y=\frac{(3)(2)+(6)(1)}{1+2}

∴ y=\frac{6+6}{3}

∴ y=\frac{12}{3}

∴ y = 4

The coordinates of the point that divides the line segment directed

from A to B in the ratio of 1 : 2 are ( 6\frac{2}{3} , 4)

ohaa [14]

Answer:

Step-by-step explanation:

Total members = 14

Each member:

Peaches = 3

Pint of cream = 1

Cost

Peaches = x cent

Pint of cream = 46 cent

46 cent = $0.46

Cost per member = 3(x cent) + 0.46

= 3x cent + 0.46

Total cost for all members = 14(3x cent + 0.46)

= 42x cent + 6.44
