Number of remaining rose cards = 6
number of remaining cards = 8
P(rose card) = 6/8
P(blue marble) = 18/50
P(tail) = 30/50
P(blue marble and tail) = 18/50 x 30/50 = 540/2500
Hello,
y=x²-x-2=x²-2*1/2*x+1/4-2-1/4=(x-1/2)²-9/4
1. Vertex=(1/2,-9/4)
2. if x=0 then y=0²-0-2=-2
3.The roots:
x²-x-2=0
==>(x-1/2)²-9/4=0
==>(x-1/2-3/2)(x-1/2+3/2)=0
==>(x-2)(x+1)=0
x=2 or x=-1
4. axe of symmetry: x=1/2
For this case we have:
: Let the variable representing the first odd number
: Let the variable representing the consecutive odd number at x.
According to the statement we have:

We found the solution by factoring:
We look for two numbers that, when multiplied, result in -63 and when added, result in 2. These numbers are +9 and -7.

Thus, we have:

Therefore the solutions are:

We choose the positive value, so we have:

Answer:
The largest number is 9
I think it is x3=2x because of the liner inequality from the graph
