Answer:
8km 5mi
Step-by-step explanation:
20x400=8000meters a km = to 1000meters
8000/1000=8km
A mile is a kilometer/ 1.6 8/1.6=5 miles
A'(1, 0 ), B'(1, 2 ), C'(3, - 2)
using the rule, add 3 to the x-coordinate and subtract 2 from the y- coordinate of the original points.
A' = (- 2 + 3, 2 - 2 ) = A'(1, 0 )
B' = (- 2 + 3, 4 - 2 ) = B'(1, 2 )
C' = (0 + 3, 0 - 2 ) = C'(3, - 2 )
<u>y=5/2x+13.5</u>
5x-2y=10
-2y=-5x+10
y= 5/2x-5
y-6=5/2(x+3)
y-6=5/2x+ 7.5
2x^2-18x
