Choose all of the equations that are equivalent to 8k = 20.

If f(x)=2x-6 and g(x)=3x+9, find (f-g)(x)

Express the following as a function of a single angle. cos(60) cos(-20) - sin(60) sin(-20)

What is the explicit formula for this sequence? -7, -4, -1, 2, a.) an = 8 + (b - 1)3 b.) an = -7 + (n - 1)3 c.) an = 3 + (n -1) (-7) d.) an = -7 + (n - )
