Because taking an absolute value of a number means making positive, then we can conclude that the absolute value of both numbers are 8.
|-8| = 8
|8| = 8
Answer:
X=4-2y/6
Y=4-6x/2
Step-by-step explanation:
For X:
1) -2y
Once you subtract 2y you are left with 6x=4-2y
2) Divide by 6 on both sides to get x alone
That would give you your answer of X=4-2y/6
For Y:
1) -6x
After subtracting 6x you would have 2y=4+6x
2) Like the steps above, you divide by 2 on both sides and that would give you your answer of Y=4-6x/2
Answer:
[4, -10, -7, -1] = [a, b, c, d]
Step-by-step explanation:
Operations of addition and subtraction on lists are generally performed term by term.
[2-(-2), -3-7, 4-11, -1-0] = [a, b, c, d]
[4, -10, -7, -1] = [a, b, c, d]
Answer:
(x - 4)
Step-by-step explanation:
Given x = a is a root then (x - a) is the corresponding factor
Given x = 4 is a root, then
(x - 4) ← is the corresponding factor
Note if x = - 4 is a root , then
(x - (- 4)), that is (x + 4) is the corresponding factor
First, pull out a factor of
.
Notice that when
(which you can arrive at via the rational root theorem), you have
which means you can pull out a factor of
. Upon dividing you get
The rational root theorem will come in handy again, suggesting that
appears a second time as a root, which means
Now this is more readily factored without having to resort to the rational root theorem. You have
so in fact,
shows up as a root for a third time.
So, you have
Two roots are obvious,
and
(with multiplicity 3). The remaining two are given by
