Answer 1

Answer:

Step-by-step explanation:

Point ( x+2 , x+4) are given in first quadrant

Then,its mirror image about an x-axis is

{x+2 ,–(x+4)} it is lies in fourth quadrant

But,here given mirror image about an x-axis

is( 5, –7) and it is also lies in fourth quadrant

So,by comparing both mirror image points

Then, we get value of x

»x+2=5 ,–(x+4)=-7

»x+2=5 , x+4=7

x=5–2=3 , x=7–4=3

Therefore,point lies in first quadrant is (5 , 7)
