If A(2,4) is reflected over the x-axis, what are it’s new coordinates ?
Sav [38]

Answer:

(2,-4)

Step-by-step explanation

When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite (its sign is changed). If you forget the rules for reflections when graphing, simply fold your paper along the x-axis (the line of reflection) to see where the new figure will be located.

Given two numbers which is always greater, LCM or GCF
ikadub [295]
" always " is the wrong word....should be sometimes

usually the LCM is greater....
example : 2 and 4.....LCM = 8, GCF = 2
                 3 and 6....LCM = 12, GCF = 3

However, if ur 2 numbers are the same...
2 and 2.....LCM = 2 and GCF = 2
4 and 4....LCM = 4 and GCF = 4
