An ellipse (by Kepler in 16th century)
The first one -8-13-18
calculate it
step by step answer!
Simplifying
Y = 230 + -45x
Solving
Y = 230 + -45x
Solving for variable 'Y'.
Move all terms containing Y to the left, all other terms to the right.
Simplifying
Y = 230 + -45x
Let,
12x + 15y =34--------(1)
-6x + 5y =3-------(2)
(2) x 2 = -12x + 10y =6-------(3)
(3) + (1)
20y =40
y= 2
substitute y=2 into (1)
12x + 15(2) =34
12x =4
x= 1/3
We have to convert the distance of 0.25 kilometers into feet. First, we convert 0.25 kilometers into meters. Since 1 kilometer has 1000 meters, we multiply 0.25 km by 1000 m/km to get 250 m. Next, 1 foot has 0.3048 m, so we divide the 250 meters by 0.3048 m/ft to get the number of feet, which is 820.21 ft.
