If y=3x+4 were changed to y=5x+4 how would the new function of the graph of the new function compare with the first one

a. it would be less steep

b. it would be steeper

c. it would be shifted up

d. it would be shifted right

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
