Select the correct answer. triangle abc underwent a sequence of transformations to give triangle a′b′c′. which transformations could not have taken place? a. a reflection across the line y = x followed by a reflection across the line y = -x b. a reflection across the x-axis followed by a reflection across the y-axis c. a rotation 180° clockwise about the origin followed by a reflection across the line y = x d. a reflection across the y-axis followed by a reflection across the x-axis

the solution is 12x-6y

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

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
