You have $12 to spend on pizza. It costs $9 plus $0.75 for each additional topping, tax included. Write and solve an inequality to find the maximum number of toppings the pizza can have.

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
