Please don't respond with the answer alone, I'd like to know how to work through it. :)
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.
49x^2-84x+k
Step-by-step explanation:
step 1. the perfect square will look like this: (7x + a)(7x + a) = (7x + a)^2.
step 2. by performing FOIL you will get 49x^2 + 14xa + a^2.
step 3. 14a = 84. a = 6
step 4. a^2 = 36.
step 5. k = 36.
