The veretx is normally the minimum value
hack:
for f(x)=ax²+bx+c
the x value of the vertex is -b/2a
so
f(x)=1x²-16x+71
x value is -(-16)/(2*1)=16/2=8
find f(8) to find y value of vertex

f(8)=8²-16(8)+71
f(8)=64-128+71
f(8)=7


the vertex is (8,7)
the minimum value is 7

#5,

it says that the angle on top is 221, so you subtract that from 360,

360-221= the rest..... 139
 Now in that 139, you can see that there is a triangle with a right angle. so you can subtract 90 degrees from 139

139-90= 49
49 is the number you use to solve the rest.
3x + 4x = 7x
so 7x = 49
and then you divide 7 from both sides to isolate x, and you get your answer

Alex17521 [72]

Student Tickets - x-64

Adult Tickets - x

x+x-64=386

2x=450

x=225

225 adult tickets were sold,

161 student tickets were sold.

Hope that helps!
