What is the domain of y = cos 1x?

[15 points, algebra 2]simplify the complex fraction and find the restrictions.

(03.03 mc) choose the graph below that correctly represents the equation 2x + 4y = 24. (5 points) select one: a. line through the points 0 comma 6 and 12 comma 0 b. line through the points 0 comma negative 6 and 12 comma 0 c. line through the points 0 comma negative 12 and 6 comma 0 d. line through the points 0 comma 12 and 6 comma 0

What is the solution to this system of equations? y= 2x - 3.5 x - 2y = -14
