What is the solution to the inequality? -3x - 14 < -5

-3x - 14 < -5

-3x < 9 (14 - 5)

x < 9: (-3)

x < -3

=> x = { -4, -5, -6, ...}

Step-by-step explanation:

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
