Give an algebraic proof for the triangle inequality vw v w +≤+ . draw a sketch. [hint: expand 2 vw vw vw + ≤+ ⋅+ ( )( ) . then use the cauchy-schwartz inequality ( vw v w ⋅ ≤ ).]

i you goofed up when writing this, because hnot is not a word minusf is not either. i cannot answer   because of that.

step-by-step explanation:

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
