Given a quadratic in standard form : y = ax² + bx + c ( a ≠ 0 ), then
The x-coordinate of the vertex is
= - 
y = 10x² + 5x - 7 is in standard form
with a = 10, b = 5 and c = - 7, hence
= -
= - 
Substitute this value into the equation for y-coordinate
y = 10 (-
)² + 5 (-
) - 7
=
-
- 7
=
-
-
= - 
vertex = (- 0.25, - 7.625 ) → E
A) will be the answer because you'll end up with two x cubed plus four x square minus twelve x
Answer:
The number of miles Mark runs in each track be 
Step-by-step explanation:
Let us assume that the number of miles Mark run in each track meet be x.
As given
Mark ran 875 miles this year in the track club.
Mark ran in 52 track meets and ran the same number of miles in each.
Than the equation becomes
52 × x = 875


Therefore the number of miles Mark runs in each track be
