56 what they said yeeeeeee
Answer:
107
Step-by-step explanation:
8b^2 - 6c + 9
Let b=4 and c=5
8*(4)^2 -6(5)+9
Exponents first
8* 16 -30 +9
Then multiply
128 -30+9
Then add and subtract
107
Answer:
x=2 x=8
Step-by-step explanation:
h(x)=-x^2+10x-16
Set this equal to 0
0=-x^2+10x-16
Divide by -1
0/-1=x^2-10x+16
0=x^2-10x+16
Factor
What two numbers multiply to 16 and add to -10
-2*-8 = 16
-2+-8 = -10
0=(x-2) (x-8)
Using the zero product property
x-2=0 x-8=0
x=2 x=8
These are the x intercepts
To get the total number of games possible, we will use the combination formula.
Total number of games :

= 45
Total of 45 games in the whole tournament.
Meanwhile, if there would be boy-versus-boy, we will have

The answer is 10.
The fraction for boy-versus-boy game will be
10/45 or 2/9 when simplified.
