Does anyone know 2x=8y=7 4x-2y=9

1 answer:

5 0

Assuming you mean 2x-8y=7, we can start by multiplying the first equation by -2 and adding it to the second (to cross out the x), resulting in -18y=-5. After that, we can divide both sides by -18, resulting in y=5/18. Next, plugging that into 4x-2y=9, we have 4x-10/18=9. Adding 10/18 to both sides, we get 4x=9+10/18. After that, we can divide both sides by 4, resulting in x=(9+10/18)/4=

The answer is c (4, 1) because when you add 1 to the x value it moves right one and then when you subtract 3 from the y value it goes down 3 making it (4, 1)

Find the values of x and y

PSYCHO15rus [73]

Hi there!

So you're looking at an equilateral triangle, which is a big word that basically means all three sides are equal and all three angles are 60°.

Knowing that, the mesure of one side is 7, so necessarily the side "x" is also equal to 7.

So the value of x is : 7

And since all angles are of 60°, necessarily the angle "y" has an angle of 60°.

So the value of y° is : 60°

There you go! I really hope this helped, if there's anything just let me know! :)
