A car can travel 27 mi for each gallon of gasoline. The function d(x)=27x represents the distance d(x), in miles, that the car can travel with x gallons of gasonline. The car's fuel tank holds 14 gal.

This is so hard and it’s for a test

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
