What are the new vertices of triangle UVW if the triangle is reflected across the y- axis?
A) U' = (-4,-4), V = (-1,-1), W' = (-3,3)
B) U' = (4,4), V' = (1,1), W' = (3,-3)
C) U' = (4,4), V = (3,1), W' = (1,-3)
D) U' = (4,-4), V = (1,-1), W' = (3,3)

the answer will be the last one

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.

answer:

c) the x-coordinate of the center of the circle increases by 3

i belive false if so your welcome if not well idk
