Intercept Form: y=2(x+3)(x-5) Standard Form? Vertex Form?

Mathematics
1 answer:
dezoksy [38]3 years ago
7 0

I'm not sure but,

Intercept Form to Standard:

y=2(x+3)(x-5)

y=[x^2-5x+3x-15]

y=[x^2-2x-15]

y=2x^2-4x-30

Standard Form to Vertex:

y=2x^2-4x-30

y=2(x^2-4)-30

y=(x^2-4x+4x)-30-4(-2)

y=2(x-2)^2-22


PS: Im clearly not sure about my answer...

What is the ratio of x to y?
abruzzese [7]
\frac{3}{2} = \frac{2x}{2x+y}

From any proportion, we get another proportion by inverting the extremes (or the means):

\frac{2x+y}{2} = \frac{2x}{3} = k

so we have:

2x=3k
2x+y=2k therefore:
3k+y=2k
y= - k

x=\frac{3}{2} k

\frac{x}{y} = - \frac{3}{2}

The corect answer is A. -3/2

or:

\frac{3}{2} = \frac{2x}{2x+y}

From any proportion, we get another proportion by inverting the extremes and the means:

\frac{2x+y}{2x} = \frac{2}{3}

We use a property of proportions:

\frac{a}{b} = \frac{c}{d}  where a, d are extremes and b,c are means and the product of the extremes equals the product of the means (a*d=b*c),

so we have

\frac{a-b}{b} = \frac{c-d}{d}  or

\frac{a+b}{b} = \frac{c+d}{d}  (you can check this also by "the product of the extremes equals the product of the means")

\frac{2x+y}{2x} = \frac{2}{3}

\frac{(2x+y)-2x}{2x} = \frac{2-3}{3}

\frac{y}{2x} = \frac{-1}{3}

3y = - 2x

\frac{x}{y} = -\frac{3}{2}
