Answer:
y = - 9, y = 3
Step-by-step explanation:
Calculate distance d using the distance formula
d = ![\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }](https://tex.z-dn.net/?f=%5Csqrt%7B%28x_%7B2%7D-x_%7B1%7D%29%5E2%2B%28y_%7B2%7D-y_%7B1%7D%29%5E2%20%20%20%20%7D)
with (x₁, y₁ ) = (2, - 3) and (x₂, y₂ ) = (10, y)
d = ![\sqrt{(10-2)^2+(y+3)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%2810-2%29%5E2%2B%28y%2B3%29%5E2%7D)
= ![\sqrt{8^2+(y+3)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B8%5E2%2B%28y%2B3%29%5E2%7D)
Given distance between points is 10, then
= 10 ( square both sides )
64 + (y + 3)² = 100 ( subtract 64 from both sides )
(y + 3)² = 36 ( take the square root of both sides )
y + 3 = ±
= ± 6 ( subtract 3 from both sides )
y = - 3 ± 6 , thus
y = - 3 - 6 = - 9
y = - 3 + 6 = 3
Answer:
66.67% or 2/3
Step-by-step explanation:
18 = 27x
x=18/27
x = 2/3
18 is 66.67% or 2/3 of 27
