What is the point that lies 1/3 of the distance from (-10, 4) to (14, -11)
Sladkaya [172]
First lets find the slope of the line that connects the two points.

\frac{y_1-y_2}{x_1-x_2}

\frac{4-(-11)}{-10-14} = -\frac{15}{24}

Now use the slope and one of the points to write the equation for the line in point-slope form.

y-y_1=m(x-x_1)

y-4= \frac{-15}{24}(x+10)

y - 4 =  -\frac{15}{24}x -  \frac{25}{4}

y = - \frac{5}{8}x -  \frac{9}{4}

The horizontal distance between the two points is 14 - (-10) = 24. We are looking for the point one-third of the way from the first point, so divide 24 by 3. The point that is a third past the first given point is 8 past x = -10. So the point has an x value of -2.

Plug x = -2 into the equation.

y= \frac{(-5)(-2)}{8}- \frac{9}{4}=-1

The answer is (-2,-1).

At the beginning of a​ walk, roberto and juanita are 7.77.7 miles apart. if they leave at the same time and walk in the same​ di
dem82 [27]
Roberto overtakes Juanita at the rate of (7.7 mi)/(11 h) = 0.7 mi/h. This is the difference in their speeds. The sum of their speeds is (7.7 mi)/1 h) = 7.7 mi/h.

Roberto walks at the rate (7.7 + 0.7)/2 = 4.2 mi/h.
Juanita walks at the rate 4.2 - 0.7 = 3.5 mi/h.


_____
In a "sum and diference" problem, one solution is half the total of the sum and difference. If we let R and J be the respective speeds of Roberto and Juanita, we have
  R + J = total speed
  R - J = difference speed
Adding these two equations, we have
  2R = (total speed + difference speed)
  R = (total speed + difference speed)2 . . . . . as computed above

Add the prices together
Then divide by 3.

*6.25 + 3.25 = 9.50/3 = 2 of them pay 3.16 while the other pays 3.17.
