Answer:
d) move 7 units to the right and 3 units down.
Step-by-step explanation:
The answer is going to be d because if you draw it out, an entire graph, and you move exactly 7 units the the right and 3 units down it should be exactly (7,-3). The answers cannot be a or b, because they're asking you to move 3 units down and up. That would give you (3,-3) which is not what they are asking for. B cannot be it either because it will give you (-7,-3) and lastly it can't be c because it'll give you the point (-3,7).
I think its the second one but just a fyi the site your on is ready and it looks like your doing the major test, not every answer on it are you suppose to get right its a test to see what you know and what you need to know
Recall the angle sum identities:
cos(a + b) = cos(a) cos(b) - sin(a) sin(b)
cos(a - b) = cos(a) cos(b) + sin(a) sin(b)
sin(a + b) = sin(a) cos(b) + sin(b) cos(a)
sin(a - b) = sin(a) cos(b) - sin(b) cos(a)
Notice that adding the first two together, and subtract the last from the third, we get two more identities:
cos(a + b) + cos(a - b) = 2 cos(a) cos(b)
sin(a + b) + sin(a - b) = 2 sin(b) cos(a)
Let a = 4x and b = x. Then
cos(5x) + cos(3x) = 2 cos(4x) cos(x)
sin(5x) - sin(3x) = 2 sin(x) cos(4x)
Now,
as required.
