The symmetric property of equality states that if two variables exist and a = b, then b = a.
So, your answer would be C (If a = b, then b = a)! :D
Answer:
If he scored x points in the first half, then x + p = 31
Answer:
Step-by-step explanation:


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
