In the given question, it is given that, the cost of telephone call, s, is $0.75 plus $0.25 times the number of minutes .
And we have to put the given informationin algebraic expression .
For the cost of telephone call, we have to use s and for the number of minutes, we need to use t .
So the required expression is
(1) x+y+z=1300
(2) x+y=780 => x = 780 - y
(3) y+z=850 => z = 850 - y
Replace x and z with y in function (1)
780 - y + y + 850 - y = 1300
1630 - y = 1300
y = 330
Therefore, x = 780 - y = 780 - 330 = 450
z = 850 - y = 850 - 330 = 520

Answer:
Step-by-step explanation:
Given
The points joining line segment are (-10,2) and (-10,-5)
Using section formula, a point joining segment divides it in k:1 has coordinates
,
Ratio is 6:1
Coordinates are
Thus, the coordinates are
