Let's solve this problem graphically. Here we have the following equation:
![sin^{-1}(4x) + sin^{-1}(3x) = -\frac{\pi}{2}](https://tex.z-dn.net/?f=sin%5E%7B-1%7D%284x%29%20%2B%20sin%5E%7B-1%7D%283x%29%20%3D%20-%5Cfrac%7B%5Cpi%7D%7B2%7D)
So we can rewrite this as:
![f(x)=sin^{-1}(4x) + sin^{-1}(3x) \\ \\ g(x)= -\frac{\pi}{2}](https://tex.z-dn.net/?f=f%28x%29%3Dsin%5E%7B-1%7D%284x%29%20%2B%20sin%5E%7B-1%7D%283x%29%20%5C%5C%20%5C%5C%20g%28x%29%3D%20-%5Cfrac%7B%5Cpi%7D%7B2%7D)
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}](https://tex.z-dn.net/?f=f%28x%29%3Dg%28x%29%20%5C%5C%20%5C%5C%20sin%5E%7B-1%7D%284x%29%20%2B%20sin%5E%7B-1%7D%283x%29%20%3D%20-%5Cfrac%7B%5Cpi%7D%7B2%7D)
Using graphing calculator, we get that this value occurs at:
![\boxed{x=-0.2}](https://tex.z-dn.net/?f=%5Cboxed%7Bx%3D-0.2%7D)
Answer:
C
Step-by-step explanation:
A coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e.g. 4 in 4x).
The 2 and + are out since they don't have variables(and the + is just a +).
So 4 and x are left. x is a variable, not a coefficient, so the last(and correct) answer is 4.

Answer:
hold on i'm abt to answer it
Step-by-step explanation:
<span>1. Find the difference
2. Divide the difference by the original number it went up from.
</span>
450-375 = 75
75/375 = 0.2
You got a 20% raise.
Proof:
375*.2 = 75
375+75 = 450
