-2 (3x - 4)= -6x - 8 true or false

Mazyrski [523]

<span>False.
-2(3x - 4) distributes to become -6x + 8
Thus, it is easy to tell it is false:

-2(3x - 4)= -6x - 8
-6x + 8 = -6x - 8
Add 6x to both sides;
8 </span>≠<span> -8</span>

If sin^-1 (x+3) = -pi/6 , x = ?

____ [38]

First recall that $\sin^{-1}x$ is defined only for $-1\le x\le1$ , which means $\sin^{-1}(x+3)$ requires that $2\le x+3\le4$ .

Over this domain, $\sin^{-1}(x+3)$ will be invertible, and so taking the sine of both sides, we have

$\sin^{-1}(x+3)=-\dfrac\pi6\implies\sin\left(\sin^{-1}(x+3)\right)=\sin\left(-\dfrac\pi6\right)$
$x+3=-\sin\dfrac\pi6$
$x+3=-\dfrac12$
$x=-\dfrac72$
