which equation best shows the relationship between x and y?

y = x + 36

y = 3x + 36

y = x + 30

y = 3x + 30

What is the measure of angle afe? 79 81 91 99

What are the solutions of the system? solve by graphing. y = x^2 + 3x + 2 y = 2x + 2

The table below represents the displacement of a fish from its reef as a function of time: time (hours) x displacement from reef (feet) y 0 4 1 64 2 124 3 184 4 244 part a: what is the y-intercept of the function, and what does this tell you about the fish? (4 points) part b: calculate the average rate of change of the function represented by the table between x = 1 to x = 3 hours, and tell what the average rate represents. (4 points) part c: what would be the domain of the function if the fish continued to swim at this rate until it traveled 724 feet from the reef? (2 points)
