Answer:
<h3>
</h3>
Step-by-step explanation:
y= x²+6x-5
completing the square: <em> a²+2ab+b²</em> <em>= (a+b)²</em> where <em>a²=x² </em>(so <em>a=x</em>) and <em>2ab=6x </em> (so <em>b</em> would be 3):
Answer:
1/2 and 13/18 respectively
Step-by-step explanation:
even-number results:
2, 4 6 ,8, 10 and 12
the combinations of each result are respectively
1+3+5+5+3+1 = 18
The total number of combinations on a roll pair is 36
then the probability of obtaining an even result is:
p = 18/36 = 1/2 or 0.5
so that the result is less than nine, we eliminate the combinations of results 9, 10, 11 and 12:
4 + 3 + 2 + 1 = 10
36 -10 = 26
the probability of obtaining a result less than nine is:
p = 26/36 = 13/18 or 0.72
Hope this helps
Answer:
x= water bottles y=cost
Step-by-step explanation:
Being that there isn't a graph, generally the top is x and the bottom is y
Y^2=x+2
here vertex = (-2,0)
+ AOS =0
Also Y= (x+2)^2
Vertex = -2,0
AOS = x+2 =0
