Answer:
1 = A 3 = b 4 = c
Step-by-step explanation:
I folded, trust me
The answer to the question is 2
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
Answer:
Step-by-step explanation:
£21000/7=3000
I got seven by adding 2 and 5
3000 times 2=6000
3000 times 5 = 15000
6000:15000
6000 for the venue
15000 for the band
