If Q is the midpoint of PR, find the coordinates of R if P(11, -2) and Q(4,3)

R = (- 3, 8 )

Step-by-step explanation:

Using the midpoint formula , equate the coordinates to the corresponding coordinates of Q.

let R = (x, y ) , then

(x + 11 ) = 4 ( multiply both sides by 2 )

x + 11 = 8 (subtract 11 from both sides )

x = - 3

(- 2 + y) = 3 ( multiply both sides by 2 )

- 2 + y = 6 ( add 2 to both sides )

y = 8

Thus

R = (- 3, 8 )

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
