Find tan x if sec x = sort 37/6 and sin x &lt;0
Sveta_85 [38]

Answer:

  tan(x) = -1/6

Step-by-step explanation:

We can use the relation between tan and sec:

  \displaystyle\tan{x}=\pm\sqrt{\sec^2{x}-1}\\\\\tan{x}=-\sqrt{\left(\dfrac{\sqrt{37}}{6}\right)^2-1}\quad\text{negative because sine is negative}\\\\=-\sqrt{\dfrac{37-36}{36}}=\boxed{-\dfrac{1}{6}}

The tangent of x is -1/6.

What is the solution to the equation -4(2x+3) = 2x+6-(8x+2)?
aivan3 [116]

Answer:

x = -8

Step-by-step explanation:

-4(2x+3) = 2x+6-(8x+2)

Distribute

-8x-12= 2x+6-8x-2

Combine like terms

-8x-12 = -6x+4

Add 8x to each side

-8x-12 +8x = -6x+4+8x

-12 = 2x+4

Subtract 4 from each side

-12-4 = 2x+4-4

-16 = 2x

Divide each side by 2

-16/2 = 2x/2

-8 =x
