Answer:

tan x

Step-by-step explanation:

(tan-x)[sec(pi/2)-x] (sin-x)

We know that tan (-x) = - tan (x)  and sin (-x) = - sin (x)

-(tanx)[sec(pi/2)-x] -(sinx)

(tanx)[sec(pi/2)-x] (sinx)

Using the identity sec = 1/ cos

sec ( pi/2 -x) =1/cos ( pi /2 -x)

We know that cos (s-t)=cos (s) cos(t) + sin (s) sin (t)

1/ ( cos  pi/2  cos x + sin pi/2 sin x) = 1/(0 cos x - 1 sinx) = 1 / sinx

Replacing into the equation

(tanx)[1/ sinx] (sinx)

tan x

Juli2301 [7.4K]
11% of $67,200.
We need to keep in mind that some words and numbers here aren't important, like 401(k) plan. 
So what is 11% of $67,200?

\frac{11}{100}  * $67,200


11*$672

-6x-4+5x=4<br> What is "x". Please show your work.
4vir4ik [10]

Answer:

first thing to do is combine like terms

now you would have -x-4=4

this is because you added -6x+5x

now you would add 4 to each side

now you would have-x=8

then you would divide the negative because x has to be positive

now you would have x= -8

that is your answer. if you any questions just ask :D
