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: 3/5
Step-by-step explanation:6/10 6 divide by 2 and 10 divide by 2
hoped this helped:)
Answer:
42
Step-by-step explanation:
Use LCM of 6 and 7 to find a number that is the same:
6 12 18 24 30 36 42
7 14 21 28 35 42
Since 42 shows up in both, the 42th voter gets a button and sticker.
Hope this helped.
x + 30 = 2x (since angleA = angle D, due to congruency between the two triangles.)
30 = 2x - x
30 = x
