PLEASE HELP The coordinates of the vertices of a quadrilateral are P (1,2), R(1,4), S(3,4),

Quadrilateral PRST is reflected across the y-axis to create quadrilateral P’R’S’T’. Which rule describes the transformation?
A) (X, Y) --> (X,-Y)
B) (X, Y) --> (-X, Y)
C) (X, Y) --> (Y,-X)
D) (X, Y) --> (-Y, X)
which one?? please help!!!

not sure but it may be b, as i said i'm not sure.

2 equivalent expressions to represent the area of a rectangle and the top is n-3 and the side is 2

area of the rectangle = length * width

given length = n - 3

width = 2

replace it in the area

so area of the rectangle = (n-3) *2

= 2(n-3)

one of the expression is 2(n-3)

to get another expression we distribute 2 inside the parenthesis

2(n-3) is 2n - 6

so another expression is 2n - 6

two equivalent expression are

2(n - 3)   , 2n - 6

answer is  

minor arc – sw

major arc – stu

semicircle – wst

i got it down chief.
