Which coefficient matrix represents a system of linear equations that has a unique solution.

What term makes it inconsistent y=2x - 4 ?

Will give brainliest immeadeately true or false: the origin woud be included in the solution set for the inequality: y< 2x-5

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)
