You will be Brainliest graph could be used to find the solution(s) to the system of equations y = log2(x – 2) and y = x3 – 2x2 – 5x + 6?

Which sum or difference identity would you use to verify that cos (180° - q) = -cos q? a.) sin (a -b) = sin a cos b – cos a sin b b.) cos (a -b) = cos a cos b – sin a sin b c.) cos (a -b) = cos a cosb + sin a sin b d.) sin (a + b) = sin a cos b + cos a sin b
