Find the missing endpoint if s is the midpoint rt. 1. r(9-4) and s(2,-1); fine t

The coordinates of point T are (13 , -6)

Step-by-step explanation:

* Lets explain how to solve the problem

- If point (x , y) is the mid point of a line whose end points are

  and , then

  and

* Lets solve the problem

∵ Point S is the mid point of segment RT

∴ S = (x , y)

∵ The coordinates of point S are (2 , -1)

∴ x = 2 and y = -1

∵ Point R =

∵ The coordinates of point R are (-9 , 4)

∴ and

∵ Point T =

- By using the rule of the mid-point above find the coordinates

 of point T

∴  

- multiply both sides by 2

∴

- Add 9 to both sides

∴

∴  

- multiply both sides by 2

∴

- Subtract 4 from both sides

∴

∴ The coordinates of point T are (13 , -6)

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
