Plz solve this problem which is mathematics models (part 2: populations dynamics)
3 populations compete for resources. r and z compete with y, but not with each other r(4-2x-y) = dt (a) find the critical point (e e, e). use routh-hurwitz to show it is unstable (b) show that the equilibrium (0.ye, z.) ? s unstable. (c) show that the equilibrium (e,0, ze) is stable (d) show that there is no equilibrium (e ye,0) (e) show that the equilibrium (0.ye.0) ? s stable. (f) all other equilibria are unstable. what does this say about the populations as

Astore manager records the total visitors and sales, in dollars, for 10 days. the data is shown in the scatter plot. what conclusion can the store manager draw based on the data? question 3 options: an increase in sales causes a decrease in visitors. an increase in sales is correlated with a decrease in visitors. an increase in visitors is correlated with an increase in sales.

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.

The boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a) e = 2b - 212 b) b = 2e - 212 c) e = -2b + 212 d) b = -2e + 212
