1. A chess player moves a knight from the location (3,2) to (5,1) on a chessboard.This means that
(3,2)→(5,1).
the translation rule is
(x,y)→(x+2,y-1) or in words 2 units right and 1 unit down.
2. If the player moves the knight from (5, 1) to (6, 3), then the translation is
(5,1)→(6,3)
and the rule is
(x,y)→(x+1,y+2).
This is translation 1 unit right and 2 units up.
Answer:
x + y < 20
5x + 10y ≥ 100
Step-by-step explanation:
The ski club wants at least $100
Student pays $5
Chaperone pays $10
Maximum number of seats = 20
Assumption:
Assumed number of students = x
Assumed number of chaperone = y
Equation:
Maximum number of seats = 20
⇒ x + y < 20
The club wants $100
⇒ 5x + 10y ≥ 100

Answer:
1,440 calories
Step-by-step explanation:
Divide 640 by 4 to get how many calories there are per scoop.
640 calories ÷ 4 scoops = 160 calories per scoop
Then, we can multiple 160 by 9 to get the calories in 9 scoops.
160 calories per scoop × 9 scoops = 1,440 calories per 9 scoops
