if you see a -x in a problem and then it says that x =-3, does that mean that when your setting up your problem you will put a positive 3 because - + -3= 3

Indicate the formula for the following conditions: p^c(n,r)=

Can you me find the slope! (30 points)

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
