You first move the constant to the left so it’s
-5x-4y+8=0
then you change the signs
5x+4y-8=0
that’s the answer

Find f(1/3) if f(n) =3n

hichkok12 [17]

Answer:

f(1/3) = 1

Step-by-step explanation:

Plug 1/3 in for n

f(1/3) = 3(1/3)

Now simplify

f(1/3) = 1 { 3(1/3) = (3/1)(1/3) = 3/3 = 1 }

Decide whether the equations is a trigonometric function identity, EXPLAIN.

hodyreva [135]

(1) Answer: Identity true

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

(2) Answer: Identity true

$\sec x \tan x(1-\sin^2x)=\sin x\\\frac{1}{\cos x}\frac{\sin x}{\cos x}(\cos^2x)=\sin x\\\sin x = \sin x$

(3) Answer: Identity true

$\sin^2(\theta)\csc^2(\theta)=\sin^2(\theta)+\cos^2(\theta)\\\sin^2(\theta)\frac{1}{\sin^2(\theta)}=\sin^2(\theta)+\cos^2(\theta)\\1 = 1$
