PLEASE HELP ME FACTOR THIS!!

Mathematics
1 answer:
Taya2010 [7]4 years ago
8 0

Answer:

  (k +2j)(4k -j)

Step-by-step explanation:

Multiply the first and last coefficients to find their product:

  (4)(-2) = -8

Factor this product until you find factors that have a sum of +7. Since you want a positive sum, it works well to start with small negative factors.

  -8 = -1×8 . . . . these have the desired sum: (-1) +(8) = +7

Now, rewrite the middle term using these factors:

  4k² -jk +8jk -2j²

Factor each pair of terms

  k(4k -j) +2j(4k -j)

Recognize these new terms have a common factor, and factor that out:

  (k +2j)(4k -j) . . . . . the factorization you're looking for

The chart below lists the original and sale prices of items at a clothing store.
Tom [10]

Answer: C) For every original price, there is exactly one sale price.

For any function, we always have any input go to exactly one output. The original price is the input while the output is the sale price. If we had an original price of say $100, and two sale prices of $90 and $80, then the question would be "which is the true sale price?" and it would be ambiguous. This is one example of how useful it is to have one output for any input. The input in question must be in the domain.

As the table shows, we do not have any repeated original prices leading to different sale prices.
