4x−4y=-2 and −9x−4y =-3 solve by adding please !!!

1 answer:

7 0

1. Add 4x back into -2, you now have -4y=-4x-2. Add +4 from y and now you are at y=-4x+2 and this is the answer!

2. Add -9x back into -3, you now have -4y=9x-3. Add +4 from y and now you are at y=9x-7 and this is your answer!!

I hope this helped! Brainliest? :) -Raven❤️

The first image has a coordinate of A'(1, 6) B'(-3, 7)

<h3>How to calculate the coordinates of an image after a translation?</h3>

Translation can be defined as movement in a straight line.

Given the rule: (x,y) → (x + 3, y - 1) and A(-2,7) B(-6,8)

That means: A(x = -2, y =7) B(x = -6, y = 8)

Thus the translation will be:

A'(-2 +3, 7-1) B'(-6+3, 8-1) = A'(1, 6) B'(-3, 7)

Therefore, the coordinate of the image is A'(1, 6) B'(-3, 7)
