Answer:

Option C is correct.

All real numbers except 9

Step-by-step explanation:

Given the function: $f(x) = \frac{x}{x-9}$

To find the domain of the function:

Domain of a function is the set of all the possible values of the independent variable.

Since, the given function is a rational function and the denominator cannot equal zero because it would be undefined.

therefore, the domain of the function f(x)is, all real numbers except 9

7 of 1010 PointsThat is the multiplicity of each of the roots of the graph of f(x) = 2x + 12r³ +16r² - 12x - 18?-3, multiplicity

Paul [167]

Solution:

Given the function;

$f(x)=2x^4+12x^3+16x^2-12x-18$

The graph of the function is;

Thus, the multiplicity of each of the roots of the graph is;

$\begin{gathered} -3,multiplicity\text{ }2; \\ \\ -1,multiplicity\text{ }1; \\ \\ 1,multiplicity\text{ }1 \end{gathered}$

Can someone please tell me what the answer is to the sentence I don't care much about the answer to the problems.

Answer:

y = x + 12

y + x = 52

x = 20

y = 32

Step-by-step explanation:

Make a system of linear equations using x and y to represent the players on the soccer and field hockey team respectively:

y = x + 12 (this shows how many players are on the hockey team)

y + x = 52 (this shows that there are 52 players total from both teams)

Solve for the variables using either elimination or substitution:

y + x = 52

(x + 12) + x = 52

2x + 12 = 52

2x = 40

x = 20

Then plug x into the first equation:

y = x + 12

y = (20) + 12

y = 20 + 12

y = 32
