Which k-value has a line that is perpendicular to the line y = 9x + 5.

The functions f (x), g (x) are defined as f (x) = 13x + 6 and g (x) = x4 + 10x2 + 18.

b) Calculate f (g (2))

For which value of a are the lines 18x 8y 36 = 5 and axes 20y + 10 = 0 parallel to each other?

Solve the equation x8= x8
