Answer:
10
Step-by-step explanation:
75c-300=25c+200
-25c -25c
50c-300=200
+300 +300
50c=500
c=10
The lateral area that Rachel needs to cover is 21 inches.
We are given:
the center of the rink at the origin.
A skating path (Susan): y = 6x - x^2 - 5
Starting point of Luke = (10, -21)
Path (Luke) = quadratic eq'n with vertex at (8, -9)
Radius = 35 meters
The solution that best interprets the path of the skaters is to substitute Luke's starting point to Susan's path or set-up a quadratic equation with vertex of (8,-9) and then equate to Susan's path to solve for their intersection.
Answer:
100
Step-by-step explanation:
(-9x+y) *5
Let x = -2 and y = 2
(-9 *-2+2) *5
Parentheses first
(18+2) * 5
(20)*5
100
Answer:
1/80
