Answer:

Question 8.)  Choice d.)  4 + x + 6x  = 4 + 7x

Question 9.) Choice b.)  18 - 15 + 4n + 5n  simplifies to  9n + 3

Step-by-step explanation:

For the first question, like terms are terms that have the same variables, and not necessarily the same coefficient numbers.

first problem,    x + y + xy  all have unique terms.  x  is different from y and is different from xy

so it cannot be A.

Choice d. has like terms  x and 6x  so  4 + x + 6x can simplify to 4 + 7x

Choice b.)  18 - 15 + 4n + 5n  simplifies to  9n + 3

victus00 [196]
Here's the factorization of the equation
f(x) = [ (x+4)(2x-1) ] / [ (x-1)(x^2+x+1) ]

<u>Domain</u>
The domain of a function is the set of input or argument values for which the function is real and defined.
- function domain : x < 1 or x > 1

<u>Range
</u>
<u />Resulting f(x) values: all Real Numbers<u>
</u>
<u>Roots
</u>
x = 1/2 & -4

<u>Axis interception points</u>
x-axis: (1/2, 0) , (-4, 0)
(y-axis): (0, 4)

<u>Asymptotes</u>
Vertical: x = 1
Horizontal: y = 0
