1) cscΘ = - 2

=>

1
------ = - 2
sinΘ

=> sinΘ = - 0.5 => Θ is in the third and fourth quadrant

=> Θ = 180° + 30° = 210°

and Θ = 360° + 30° = 330°

2) tan Θ = √3

=> Θ = 60° and Θ = 180° + 60° = 240°

How do you solve this math problem-2(x+3y)=18

ss7ja [257]

Greetings!

Solve for <em>x</em>.
$-2(x+3y)=18$
Distribute the Parenthesis. <em>How?</em> Multiply all of the terms inside the parenthesis by the number outside the parenthesis.
$(-2)*x+(-2)*3y=18$
$-2x-6y=18$
Add 6y to both sides.
$(-2x-6y)+6y=(18)+6y$
$-2x=18+6y$
Divide both sides by -2.
$(-2x)/-2=(18+6y)/-2$
The Answer Is:
$x=-9-3y$
$x=-3y-9$

Hope this helps.

Subtract 2xy-8 from 5x^2+3xy+12

JulijaS [17]

Answer:

5x^2 + xy + 20

Step-by-step explanation:

Begin with 5x^2+3xy+12, Subtracting 2xy yields 5x^2 + xy + 12. Next, subtracting -8 yields 5x^2 + xy + 12 - (-8), or 5x^2 + xy + 20
