The perimeter of a rectangle is 400 meters. The length is 15 meters less than 4 times the width. Find the length and width.

Which number line represents the solution set for the inequality -1/2x> 24?

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)

I'm confused on this could anyone me and show me what i need to do to solve it.
