It is 9 weeks. 8 times 12 is only 96$
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
First you want to get the x's on the same side
3x-5=2x+6
subtract 2x and add 5
x=11
Hope this helps!
Answer:
40 and 10
Step-by-step explanation:
if you add them you get 50 and if you subtract them you get 30
I would classify that shape as a pentagon because it has 5 sides/edges.
It is shaped like the houses in the old times.
Hope I helped :) :)
