What are three equivalent ratios 14/2

Taya2010 [7]

Answer:

7/1
21/3
532/76

Step-by-step explanation:

Reduce the ratio to lowest terms, then multiply numerator and denominator by any same value to get another equivalent.

$\dfrac{14}{2}=\dfrac{2\cdot 7}{2\cdot 1}=\dfrac{7}{1}\\\\=\dfrac{3\cdot 7}{3\cdot 1}=\dfrac{21}{3}\\\\=\dfrac{76\cdot 7}{76\cdot 1}=\dfrac{532}{76}$

Write y=2x^2+12x+14 In vertex form

ratelena [41]

Answer:

$\large\boxed{y=2(x+3)^2-6}$

Step-by-step explanation:

The vertex form of a parabola f(x) = ax² + bx + c:

$y=a(x-h)^2+k$

(h, k) - vertex

$h=\dfrac{-b}{2a}\\\\k=f(h)$

We have the equation:

$y=2x^2+12x+14\\\\a=2,\ b=12,\ c=14\\\\h=\dfrac{-12}{2(2)}=\dfrac{-12}{4}=-3\\\\k=f(-3)=2(-3)^2+12(-3)+12=2(9)-36+12=18-36+12=-6$

Finally:

$y=2(x-(-3))^2+(-6)=2(x+3)^2-6$
