Answer:
y=-0.215x^2+35
Step by Step:
Let,
,
,
, 
We know that, the general equation of the parabola.


Substitute the value of
in equation
and find the value of 







Hence, the equation of the parabola is:

The answer is C, because to find IQR you have to find the difference (subtract) of the first and third quartile
Answer: x = 14 - 5y
y = 14/5 - x/5( if you solve for y )
2nd one x = 35/4 + y/4
y = -35 +4x ( solve for y )
