12(28980) = 180(x)
347760 = 180x
347760/180=1932
7.211; Starting from the left to right, x1=3 x2=7, y1=2 y2=8. Plug these in to the distance formula 
(7-3)^2+(8-2)^2
(4)^2+(6)^2
16+36
sqrt 52
7.211
The graph of a quadratic equation is a U-shaped curved called parabola. It is because the parabola makes very easy to find the axis of symmetry to plot selected points and finding the roots and vertex.
Good luck :)
Your problem is:
$35.00 is what percentage of $437.50?
If you are given a part and the whole, and you want to know what percent the part is of the whole, divide the part by the whole and multiply by 100.
In this case, the whole is $437.50.
The part is $35.00.
35/437.5 * 100 = 8%
the answer is D. hope this helps :))
