The left sides of the equations are the same and the right sides of the equations are different, therefore the system of equations is inconsistent.
Answer: B. inconsistent.
Answer:
H is less than of equal to 8
Step-by-step explanation:
As anoutline, angles O and Q are inscribed angles which are measured by one-half of its intercepted arc.
angle O = 1/2 arc RQP
angle Q = 1/2 arc ROP
so arcs RQP and ROP together make up the entire circle which has 360 degrees.
so angles O and Q is 1/2 (360) = 180 degrees (supplementary angles).
recall that to get the inverse of any expression, we start off by doing a quick switcheroo on the variables, and then solve for "y".
![\bf \stackrel{f(x)}{y}=2x\implies \stackrel{\textit{switcheroo}}{x=2y}\implies \cfrac{x}{2}=y\implies \cfrac{1}{2}x=\stackrel{f^{-1}(x)}{y}](https://tex.z-dn.net/?f=%5Cbf%20%5Cstackrel%7Bf%28x%29%7D%7By%7D%3D2x%5Cimplies%20%5Cstackrel%7B%5Ctextit%7Bswitcheroo%7D%7D%7Bx%3D2y%7D%5Cimplies%20%5Ccfrac%7Bx%7D%7B2%7D%3Dy%5Cimplies%20%5Ccfrac%7B1%7D%7B2%7Dx%3D%5Cstackrel%7Bf%5E%7B-1%7D%28x%29%7D%7By%7D)
