Find two numbers that multiply to -28 (last term) and add to -3 (middle term)
Those two values are -7 and 4
-7 plus 4 = -3
-7 times 4 = -28
Since the numbers are -7 and 4, this means the given expression factors to (x-7)(x+4)
The two factors are x-7 and x+4
The factor x+4 isn't listed in the list of answer choices, so we can ignore it. The factor x-7 is listed as choice B, so that is the only answer.
Answer:
1
Explanation:
According to the Unit Circle, sin π\6 is ½, so we plug this into the cosine function to get this:
cos π\6 - π\6 → cos 0 >> 1

*** Plus, we need to make sure that the x-value falls in between 0 and π\2, which it did, so no need to worry.
At least 15 b/c is you add QWERTY to -12, you get zero and adding 5 to get 15 in total.
I don't see a table but I can give you the means to answer it yourself. The inverse function is represented by this:
where k is your constant. You are given a k value of 4. If you solve this for k then you will get xy=4. In your tables, multiply your x value by your y value within your coordinate points and if you get a product of 4 each time you multiply x by y, then that table is your answer.
