Asailboat travels a distance of 2 1/2 miles in 1/6 of an hour. which complex fraction represents the unit rate in miles per hour? a: 2/12 / 1/6b: 5/2 / 1/6c: 1/6 / 5/2d: 1/6 / 2 1/2

for the points! : )

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form

i believe your answer is a

okey so the slope is -3/5 and the y -intercept is 7/5

hope this if needed hmu
