Answer:
-8 ≤ x ≤ -1
Step-by-step explanation:
When working with inequalities, closed circles always represent greater than or equal to and less than or equal to signs.
The x is placed between the -8 and the -1, as it represents all numbers greater than -8 and less than -1
Answer:
B.
Step-by-step explanation:
Since she had 22 dollars but only put in 2 $5 bills, you would subtract 22 by 10, which means she already had 12 dollars in her piggy bank from before. The $12 is also the constant now. However many $5 bills she puts in her piggy bank has to be multiplied by 5 because that is the value of the bill.
Start by taking out a common factor.
x^10
x^10(x^6 - 2x^5 - x^4 + 4x^3 - x^2 - 2x + 1) = 0
So far we know that D won't work.
x - 1 is a factor because putting 1 in for the xs in the expression inside the brackets gives 0 Now you need to do a division. I'm going to assume you can do that.
Using division, I get
x^5 - x^4 - 2x^3 + 2x^2 + x - 1 Now divide x - 1 into this mess again. You get
x^4 - 2x^2 + 1 which factors into
(x^2 - 1)(x^2 - 1) which factors into
(x - 1)(x + 1)(x - 1)(x + 1) = 0
The first two divisions add (x -1)(x - 1)
========================
So we have (x - 1) with a multiplicity of 4 and (x + 1) with a multiplicity of 2
or x = 1 with a multiplicity of 4 and x = -1 with a multiplicity of 2 and x = 0
with a multiplicity of 10
That's the answer.
