Help me please help me, I need the answer because only have 1 hour for finish and my grqades is so bads and these is extra credit please if you don't know the answer don't answer, the homework is in the link https://web. kamihq. com/web/viewer. html?state=%7B%22ids%22%3A%5B%221AD dpUXkqfhfov4E7Ja2VmvY_dGmqDqRu%22%5 D%2C%22authuser%22%3A%220%22%2C%22f rom%22%3A%22classroomopenext%22%7D& amp;kami_user_id=7473954

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer

~

y -5 = (-1/4)(x + 8)

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
