X = y−4, 2x−5y = 3

1 answer:

5 0

X=y-4 Let's make this eqn 1 and

2x-5y=3 this eqn 2..

Two things are possible here...
Its either you substitute for x in equation 2... Or you substitute for y...

x=y-4 put this in the equation 2..

2x-5y=3.. Replace the x with (y-4)

2(y-4)-5y = 3...
Since this is In the option no point in substituting for y...

Hope this helped...?

ABC will undergo two transformations to give abc. Which pair of transformations will give a different image of abc if the order

ExtremeBDS [4]

You can consider the triangle (as on in the picture) and apply to it composition of two transformations:
1. reflection about the line y=x to form ΔA'B'C' and translation 1 unit right and 5 units up to form ΔA''B''C'';
2. translation 1 unit right and 5 units up to form ΔA'B'C' and reflection about the line y=x to form ΔA''B''C''.
You can see that results are different.

On added picture blue colour responds to composition of transformations 1 and red colour to composition of transformations 2.
