Answer:

-9/2; third graph

Step-by-step explanation:

-17 + (1/3)x = - 18 1/2 is to be solved for x.

First, identify the LCD: It is 6. Multiply all terms by 6:

-102 + 2x = -111

Next, add 102 to both sides, to isolate the 2x term:

2x = -111 + 102 = -9

Finally, divide both sides by 2, obtaining

x = -9/2

This is shown in the third graph.

Simplify and write the trig expression in terms of sin and cos

We have:

$cot(-x)cos(-x)+sin(-x)=-\frac{1}{f(x)}$

Then we use trigonometric identities to change the negative sign of the trigonometric functions, so:

$-sin(x)-cot(x)cos(x)=-\frac{1}{f(x)}$

We clear f(x):

$f(x)=\frac{1}{sin(x)+cot(x)cos(x)}=\frac{1}{sin(x)+\frac{cos(x)}{sin(x)}cos(x)}=\frac{1}{sin(x)+\frac{cos^2(x)}{sin(x)}}$

we simply what we can:

$f(x)=\frac{1}{\frac{sin^2(x)+cos^2(x)}{sin(x)}}=sin(x)$

Thus, the correct answer is;

$f(x)=sin(x)$
