( - 10, - 22 )
using the midpoint formula,
let the other endpoint have coordinates (x, y) then
(2 + x ) = - 4 ( multiply through by 2 )
2 + x = - 8 ( subtract 2 from both sides ) then
x = -8 - 2 = - 10 ← value of x-coordinate
Similarly for y-coordinate
(8 + y ) = - 7 ( multiply through by 2 )
8 + y = - 14 ( subtract 8 from both sides )
y = - 14 - 8 = - 22 ← y -coordinate
the other endpoint is ( - 10, - 22 )
1) with the formula V=X/T, where X is distance and T is time you can verify with speed is greater
the speed of Emma is V = 3/4÷6 , V = 3/4 × 1/6 = 3/24 ⇒V = 1/8 m/h
the distance of joanie is 1 + 1/2 = 3/2 now the speed of Joanie is V= (3/2) ÷11 , V = (3/2)÷11 , V = 3/22 m/h
as 1/8 = 0.125 and 3/22 = 0.136 then the speed of joannie is greater than Emma

Step-by-step explanation:
the greatest possible error for meters is 1/2 the increments
since 18.9 is to the tenths place
1/2 x 1/10 = 0.05
so greatest possible error for 18.9 is 0.05m
Answer:
2√2
Step-by-step explanation:
The area ratio is the square of the side length ratio, so the ratio of side lengths is √2.
The volume ratio is the cube of the side length ratio, so the new cube has a volume that is (√2)³ times that of the original.
The volume ratio is 2√2.
