B1=x=133andy=133
B2=53,61,and 56
B3=x=37andy= 37
B4=x=54and y=68
C1=y= 43and x=51
Answer:

Step-by-step explanation:
Where p is the distance from focus to vertex, the equation of the parabola with focus at (0, p) is ...

Your parabola has p=9, so the equation is ...

Answer:
Associative property
Step-by-step explanation:
When x=3, y=9 and when x=6, y=3 bc u plug them into the equation
4/3 = 320/x
4x = 320*3
4x = 960
x = 240
Check:
320/240 divide both by 80
= 4/3 :)
