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

Which of the following rational functions is graphed below?
Zepler [3.9K]

Answer:

  D.  F(x) = 1/(x +5)²

Step-by-step explanation:

The vertical asymptote at x=-5 tells you that x=-5 will be a zero of the denominator. The only equation with a denominator factor of (x+5) is ...

  F(x) = 1/(x +5)²

_____

<em>Additional comment</em>

The fact that the value of F(x) does not change sign at the vertical asymptote tells you the denominator factor will be of even degree. That is taken for granted here, as all denominators are squares in the answer choices.
