Write two addition sentences where the sum is negetive. in each sentence, one addend should be positive and the other negetive.

What is the equation of a line passing through the point (6,1) and parallel to the line whose equation 3x=2y+4

What are the solutions of the system? solve by graphing. y = -x^2 - 3x + 2 y = -2x + 2

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
