<h2>Explanation:</h2><h2></h2>

Let's solve this problem graphically. Here we have the following equation:

$sin^{-1}(4x) + sin^{-1}(3x) = -\frac{\pi}{2}$

So we can rewrite this as:

$f(x)=sin^{-1}(4x) + sin^{-1}(3x) \\ \\ g(x)= -\frac{\pi}{2}$

So the solution to the equation is the x-value at which the functions f and g intersect. In other words:

$f(x)=g(x) \\ \\ sin^{-1}(4x) + sin^{-1}(3x) = -\frac{\pi}{2}$

Using graphing calculator, we get that this value occurs at:

$\boxed{x=-0.2}$

Answer:

$4x^2(x-2)(x+6)$

Step-by-step explanation:

Factor $4x^2$

$4x^2(x^2)+4x^2(4x)-4x^2(-12)$

$4x^2(x^2+4x-12)$

$4x^2(x-2)(x+6)$

The variables x and y vary inversely, and x = 12 when y = 6. Use the inverse variation formula, k = xy, to

I am Lyosha [343]

Answer:

D=24

Step-by-step explanation:

y inversely as x

x=k/y

By cross multiplication

k=xy

k=12*6

k=72

finding y

72=3y

y=24
