Find the solution of the Quadratic Equation X^2 -5X - 14 = 0 note: X^2 means x to the power of 2

What values of x satisfy the inequality x^2-9x< 0? how is your answer shown on the graph?

How do you determine whether a relationship represented as as graph is linear or nonlinear

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)
