Which equation has a graph that is a parabola with a vertex at (–2, 0)?
RideAnS [48]

Comparing to the standard equation, the parabola with a vertex at (-2,0) is given by:

y = (x + 2)²

<h3>What is the equation of a parabola given it’s vertex?</h3>

The equation of a quadratic function, of vertex (h,k), is given by:

y = a(x - h)² + k

In which a is the leading coefficient.

In this problem, we have that h = -2 and k = 0, and all the options have leading coefficient a = 1, hence the equation is:

y = (x + 2)²

What is 46 2/3% of 28?
lilavasa [31]

46 2/3 %

= (46 + 2/3)/100

= (138/3 + 2/3)/100

= (140/3)/100

= 140/300

= 7/15

So it's

7/15 * 28

= 196/15

= 15 1/13
