M= 1/2x+6
N= 1/2x-3
They both have the same slope.
Hence, the correct option is (D)There are no extraneous solutions to the equation.

Answer:
question 1: answer is 4
question 2: answer is 1
Step-by-step explanation:
Cos(2x) = cos^2(x) - sin^2(x) - cos(x)
but sin^2(x) = 1 - cos^2(x)
cos(2x) - cos(x) = cos^2(x) - (1 - cos^2(x) ) - cos(x)
cos(2x) - cos(x) = cos^2(x) - 1 + cos^2(x) - cos(x)
cos(2x) - cos(x) = 2cos^2(x) - 1 - cos(x)
cos(2x) - cos(x) = (2cos(x) + 1)(cos(x) - 1)
I think this is what you have asked for.
