Answer: $1.19X+ 4.99
then :$15.7
Step-by-step explanation: first you write the expression which is $1.19X + 4.99 because $1.19 is the cost of per song download and X stands for the numer of songs .
then after you khow the expression you substitute ( which meanse to put something instead of a variable like X) 9 because 9 is the total number of song
that how you get $15.7 if you substutute 9 with X.
hi . i hope the explanation is helpful to you .
Step-by-step explanation:

The binomial theorem states that for some a,b∈R and some k ∈Z+ ,
(a+b)k=∑n=0k(kn)ak−nbn.
The binomial series allows us to use the binomial theorem for instances when k is not a positive integer. The binomial series applies to a given function f(x)=(1+x)k for any k∈R with the condition that |x|<1 . It is stated as follows:
(1+x)k=∑n=0∞(kn)xn .
Note that the binomial theorem produces a finite sum and the binomial series produces an infinite sum.
Answer: B
Reason:
44 + x
66
x
22
Also when we have a greater and equal to sign (
), it will be a filled in circle.
Thats why its by.
<span>5-x=12
Subtract 5 from both sides
-x=7
Divide -1 on both sides so that the only thing remaining is x alone
Final Answer: x= -7</span>
SEE ATTACHED IMAGE TO OBSERVE THE GRAPH OF THE FUNCTION.
For this case, the first thing we should see are the cut points with the x axis.
We note that the graph cuts to the x-axis at x = -2
Therefore, x = -2 is the real solution to the polynomial.
Also this function:
x3 + 6x2 + 12x + 8
It can be rewritten as:
(x + 2) ^ 3
From where we conclude that its roots are:
x = -2 (with multiplicity 3)
Answer:
the equation x3 + 6x2 + 12x + 8 = 0 have:
x = -2
As a real solution with multiplicity 3.
