21. the midpoint of uv is (5,-11). the coordinates of one endpoint are u(3,5). find the coordinates of endpoint v.

(7,-27)

Step-by-step explanation:

The coordinates of mid point of a line segment having endpoints (a,b) and (c,d) is given by :-

Given : The midpoint of UV is (5,-11). The coordinates of one endpoint are U(3,5).

Let the coordinates of endpoint V be (a,b), then we have

 [Multiply 2 both sides]

Hence, the coordinates of endpoint V = (7,-27)

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
