2. Solve the following system of ODEs without using Laplace transforms: $$ \begin{cases} \frac{dx}{dt} = 3x + 2y + 1 \\ \frac{dy}{dt} = 4x - y - 2. \end{cases} $$ Find the general solution and clearly indicate: * Critical Points: All equilibrium points and classify them. * Stability Analysis: Analysis and stability of critical point(s). * Straight-Line Trajectories: The equation of straight-line trajectories. * Phase Portrait: Sketch the trajectories near the critical points, labeling the direction of flow and the stability type (e.g., stable, unstable).

Why is the bone density sacrificed to maintain homeostasis of blood calcium? O Bone density IS NOT sacrificed to maintain blood levels of calcium O Older populations have better intake of calcium than younger people O Bone contains minerals not found in the diet O Osteopenia / osteoporosis is not immediately life-threatening and low levels of calcium in the blood is
Which statement is true about the Council-Manager form of government? Since each board member is elected by the people, they are free to go out and represent the city in anway they feel is appropriate, including obligating expenses on behalf of the city.

Recent supply chain issues have set his company back in profits, and JB is struggling. He has an opportunity to fill the trucking/delivery shortage for a 6- month period but will require his drivers and employees to work longer days and be away from home more. But this will make them profitable and avoid shutting the company down. 1) List at least five motivation techniques JB can use to motivate his employees to work hard for 6 months? 2) What goals can JB set to motivate his drivers? 3) Is JB being fair to push his drivers so hard, explain? 4) Should JB take inputs from his employees, or just execute his own plan, explain?
Jocelyn is pregnant and needs to eat at least 600 more calories a day than usual. When buying groceries one day with a budget of $20.00 for extra food, she buys bananas that have 50 calories each and granola bars that have 120 calories each. The bananas cost $0.75 each and the granola bars cost $2.50 each. Write a system of 2 inequalities to model this situation. Use "z" for the number of bananas and "y" for the number of granola bars. First Inequality: Second Inequality:
