Answer:

D. reflection across a vertical line

Step-by-step explanation:

Reflection is basically a mirror image. Since you can see that the first triangle is flipped over to get the second one, this is a reflection.

It is not a vertical translation; this means that the triangle shifted up or down.

It is not a horizontal translation, this means that the triangle shifted left or right.

It is not a rotation about point A either, this would have meant that the triangle spun around.

One brother says of his younger brother: “Two years ago, I was three times as old as my brother was. In three years’ time, I wil
aleksklad [387]

Answer:

17

Step-by-step explanation:

Let us suppose two years ago my brother's age was x years

Then, my age was 3x

Three years from now, my brother's age will be (x +2+3) = (x+5) years

And my age will be (3x+2+3) = (3x+5) years

But it is given that i will be twice as old as my brother.

So, 2(x+5)= (3x+5)

or, x= 5 years

So my brother's present age is 5+2= 7 years

And my age is 5*3+2= 17 years
