What are the coordinates of point C on the directed segment from A (-8,4) to B (10,2) that partitions the segment such that AC:C

Burka [1]

Answer:

(14/3, 8/3)

Step-by-step explanation:

Let the points be

$(x_1,y_1) = A(-8,4)\\(x_2,y_2) = B(10,2)\\$

The formula for finding the coordinates of point that divides the line in a:b is:

$x = \frac{bx_1+ax_2}{a+b} \\y = \frac{by_1+ay_2}{a+b}$

Here x and y are the coordinates of the point that will partition the line into given ratios

Our ratio is 2 to 1,

So,

a=2

b=1

Putting the values in the formula

$x = \frac{(1)(-8)+(2)(10)}{2+1}\\x = \frac{-8+20}{3}\\x =\frac{14}{3}\\y = \frac{(1)(4)+(2)(2)}{3}\\y=\frac{4+4}{3} \\y= \frac{8}{3}$

So the coordinates of point that divides AB in 2:1 are:

(14/3, 8/3) ..

Answer:

Step-by-step explanation:

In the equation it states there is a one-time fee charge so we would add this when writing it in an expression. Since the expressions is: T = 15n + 12; and the only number being added is 12, we can assume the number 12 represents the service fee cost.
