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

step by step

(7, -27)

Step-by-step explanation:

Use the midpoint formula.

M = ( x₂ + x₁ , y₂ + y₁)  / 2

(5, -11) = (x₂ + 3 , y₂ + 5)  / 2       Substitute the midpoint and point U.

(10 , -22) = (x₂ + 3 , y₂ + 5)        Multiply by 2 on both sides

x₂ + 3 = 10        y₂ + 5 = -22     Split for each point and solve.

x₂ = 10 - 3         y₂ = -22 - 5    

x₂ = 7                y₂ = -27

Point V is (7, -27).

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

i believe the correct answer is option 4.principalities were small territories that were run by russian rulers.

which statement correctly defines principalities in northern asia in the 1200s? principalities were small territories that were run by russian rulers.

hope i could ! : )
