Eugene has to buy cupcakes for a picnic. he needs to make sure that there are more than 8 cupcakes so each of his friends gets at least one cupcake. if eugene buys y boxes that each contain 4 cupcakes, which inequality represents this situation? a. y < 8 b. y > 8 c. 4y > 8 d. 4y < 8

What is the equation of the line in point-slope form? y+ 4 = 1/2(x+4) y-4 = 1/2(x + 4) y-0 = 2(x - 4) y-4 = 2(8-0)

The position of a moving particle is given by the position function: f(t)=-9t-t^2-0.2t^3+0.1t^4 0 a. at what time does the particle reverse direction? b. when is the displacement positive? (round one decimal place and answer in interval notation) c. when is the displacement negative? (round one decimal place and answer in interval notation) d. when is the particle’s acceleration positive? (round one decimal place and answer in interval notation) e. when is the particle’s acceleration negative? (round one decimal place and answer in interval notation)

Rewrite so the subject can be y in the formula d=m-y/y+n
