Let the number be x.
Half of that number = x / 2
One third of the number = x / 3
= x / 2 + x / 3 = 22. LCM = 6.
= (3x + 2 x) / 6 = 22.
5x / 6 = 22. Cross multiply
5x = 6 * 22.
5x = 132 Divide both sides by 5.
x = 132 / 5
x = 26.4
The number is 26.4. Cheers.

Hope this helps! (tried to do an explanation and my browser crashed...) </span>
You just have to look at the form of the equations
The only linear equations would be y = mx + b and Ax + By = C
I do belive i did my math correct and I n.v should be the top one
A quadratic equation may be expressed in vertex form as:
y = a(x - h)² + k, the vertex being (-h , k)
For option A, the vertices are visibly different. (-4 , 0) and (4 , 0)
For B, the graphs' vertices are the same, (0 , 0).
For C, the vertices (can be obtained by differentiating and putting equal to 0) are (0 , -4) and (0 , 4)
For D, the vertices are (4 , 0) and (0 , 4)
Thus, the answer is B.
