What is the slope of the line with the equation 0 = -15x + 6y

15/6

Step-by-step explanation:

if ax^2+bc+c=0 is given equation then slope of this equation will be

m=-a/b

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92

he has 140 chickens because he has 10 times more chickens than ducks and he has 14 ducks so 14*10=140
