Answer to -5x-6x<8-8n-n

EastWind [94]

First...
$Simplify\;-5x-6x \ \textgreater \ \mathrm{Add\:similar\:elements:}\:-5x-6x=-11x$

$Simplify\;8-8n-n \ \textgreater \ \mathrm{Add\:similar\:elements:}\:-8n-n=-9n$
$8 - 9n$

$-11x\ \textless \ 8-9n$

$\mathrm{Multiply\:both\:sides\:by\:-1\:\left(reverse\:the\:inequality\right)} \ \textgreater \ 11x\ \textgreater \ -8+9n$

$\mathrm{Divide\:both\:sides\:by\:}11 \ \textgreater \ \frac{11x}{11}\ \textgreater \ -\frac{8}{11}+\frac{9n}{11}$

$Simplify \ \textgreater \ x\ \textgreater \ \frac{-8+9n}{11}$

Hope this helps!

Which of the following is a solution to tan^2 x-1=0? a.45 degrees, b.120 degrees, c.240 degrees, d.330 degrees

andrew-mc [135]

Do you want a general solution or from 0 <= x < 2pi?

tan^2(2x) - 1 = 0
tan^2(2x) = 1

Take the square root of both sides,

tan(2x) = +/- 1

Two equations:
tan(2x) = 1
tan(2x) = -1

Solve each equation.

tan(2x) = 1, 2x = {pi/4, 5pi/4, 9pi/4, 13pi/4},
x = { pi/8, 5pi/8, 9pi/8, 13pi/8 }

tan(2x) = -1, 2x = { 3pi/4, 7pi/4, 11pi/4, 15pi/4 },
x = { 3pi/8, 7pi/8, 11pi/8, 15pi/8}

So for solutions within [0, 2pi),

x = {pi/8, 3pi/8, 5pi/8, 7pi/8, 9pi/8, 11pi/8, 13pi/8, 15pi/8 }

Find all of the solutions for the following equation. 2 sin 0 + 3 = sin 0 + 2

den301095 [7]

Answer:

Step-by-step explanation:

$2 sin \theta+3=sin \theta+2\\sin \theta=-1=sin 270,sin(360n+270)\\\theta=270,360 n+270 where n is an integer.$
