The answer

the complement of the question is

What is the value of y?

2
5
7
8

According to the image, HKJ and FGH are similar, we can apply the theorem of thales
since GK and GF are parallels, so

HK / HF = HJ / HG = KJ / GF and as we see on the figure, HK = HF /2, this implies 2HK =HF

HK / 2HK = KJ / GF it is equivalent to 1/2 = 2y+5 / 5y +3

likewise, equivalent to 5y +3 = 4y +10, 5y-4y = 10-3, and y = 7

so the answer is 7

Olegator [25]

Answer:

It's a parabola

Step-by-step explanation:

If you write the equation as

x =3y2

, you can see that you are in the form

f (y)=3y2

. This is a quadratic polynomial in

, which means that it represents a parabola with axis parallel to the

x axis.
