Px + qy = r
2px - qy = 2r
----------------add
3px = 3r
x = 3r/3p
x = r/p
According to my calculations,
A. is the correct answer.
8√5
Simple, solve straight across, its either 4n or 2n
Answer:
(- 1, - 1 )
Step-by-step explanation:
under a reflection in the x- axis
a point (x, y ) → (x, - y ) , then
(- 1, 4 ) → (- 1, - 4 )
a translation of 3 units up means adding 3 to the y- coordinate , so
(- 1, - 4 ) → (- 1, - 4 + 3 ) → (- 1, - 1 )
