8x + 4y = 20

4y = 20 - 8x

y = 5 - 2x

I think your answer would be y=-2x+5 all you have to do is rewrite it in slope intercept form y=mx+b

It would be 7:9 because if you divide each side by 4 then you can get it in simplest form

ANSWER

$12y \sqrt{3}$

EXPLANATION

The given expression is

$\sqrt{3y^2} + 4\sqrt{12y^2} - y\sqrt{75}$

We identity and remove the perfect squares to obtain

$y\sqrt{3} + 16y\sqrt{3} - 5y\sqrt{3}$

We now observe that, the three terms are all similar.

We combine the similar terms to get:

$y\sqrt{3} + 16y\sqrt{3} - 5y\sqrt{3} = 12y \sqrt{3}$
