Answer:
since you recorded the first marble then replaced it, you drew 10 blue marbles, so therefore we can predict the next marble you drew, was blue.
Step-by-step explanation:
Hello DestinyKiara99 o/
We can solve this equation using the quadratic formula
Check it out...
x² + 6x - 24 = 0
Δ = 6² - 4.1.(-24)
Δ = 36 + 96
Δ = 132
x = -6 +/- √132 x' = -3 + √33
<span> -------------- /
2 \
x'' = - 3 - </span>√33
The correct answer is the letter D
I hope this help =)
47 -14i
You can work this out in the straight-forward way, or you can recognize that (6-i) is a common factor. In the latter case, you have ...
... = (6-i)(5 + 3-i)
... = (6 -i)(8 -i)
This product of binomials is found in the usual way. Each term of one factor is multiplied by each term of the other factor and the results summed. Of course, i = √-1, so i² = -1.
... = 6·8 -6i -8i +i²
... = 48 -14i -1
... =

A suitable graphing calculator will work these complex number problems easily.
Plug in the 6 and -1 to get the answers
f(6)=120
f(-1)= 8
