Triangle xyz is reflected across the y-axis, and x = (4, –5). what are the coordinates of x’ ?

Co-ordinates of X' are (-4,-5).

Step-by-step explanation:

We are given a triangle XYZ with co-ordinates of X = (4,-5).

Also, it is given that, XYZ is reflected across y-axis.

We know, 'When a figure is reflected across y-axis, the co-ordinates (x,y) changes to (-x,y)'.

So, as XYZ is reflected across y-axis.

We get,

X = (4,-5) changes to X' = (-4,-5)

Hence, the co-ordinates of X' are (-4,-5).

my answer is$ 12

step-by-step explanation:

because 15 -2=12

for me what is finding a good play list and going out because i can not lay down and relax so i usually go to a coffee shop. i also use the gum trick and this actually works. another advice is highlighting subjects it really does me remember certain things
