The point A(7, -3) is reflected over the point (6, -5) and it's image is point B. What are the coordinates of point B?

Solve x+3y=6 and 4x-6y=6 by elimination . show work !

Use composition to determine if (x) or h(x) is the inverse of f(x) for the limited domain x2-1.

Prove (a) cosh2(x) − sinh2(x) = 1 and (b) 1 − tanh 2(x) = sech 2(x). solution (a) cosh2(x) − sinh2(x) = ex + e−x 2 2 − 2 = e2x + 2 + e−2x 4 − = 4 = . (b) we start with the identity proved in part (a): cosh2(x) − sinh2(x) = 1. if we divide both sides by cosh2(x), we get 1 − sinh2(x) cosh2(x) = 1 or 1 − tanh 2(x) = .
