Let r be the red marble, b the blue marble, g the green marble.
possible outcomes={r,r,b,b,b,b,b,b,b,g,g,g,g,g,g}
total=15
2/15=.133 is the probability

Help solve equations by completing the square
Allushta [10]

x^2+10x+22=13\\x^2+10x+22-13=0\\x^2+10x+9=0\\

Now completing the square.

(x^2+10x)+9=0\\(x^2+10x+25)+9-25=0\\(x+5)^2-16=0\\(x+5)^2=16

(x+5)² = 16 is the rewritten equation... For first question btw.

For the solutions to the equation -

x+5=\sqrt{16},-\sqrt{16} \\x+5=4,-4\\x=4-5,-4-5\\x=-1,-9

x = -1,-9 is the solution, for the second question.

2. f(x)=4x+1 and ​g(x)=x2−4x−5​, find ​(g◦​f)(4​).
Goryan [66]

Answer:

(g · f)(4) = 45

Step-by-step explanation:

f(x)=4x+1

g(x)=x² - 4x- 5

(g · f)(x) = 4(x² - 5) + 1

(g · f)(4) = 4(4² - 5) + 1

Following pemdas

(g · f)(4) = 4(16 - 5) + 1

(g · f)(4) = 4(11) + 1

(g · f)(4) = 44 + 1

(g · f)(4) = 45
