A middle school took all of its 6th grade students on a field trip to see a symphony. The students filled 300 seats, which was 10% of the total number of seats in the theatre. How many total seats were in the theatre?

If f(x)=3x+1 and f^-1=x-1/3, then f^-1(7)=

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)

What is the value of x in the equation 1.5x+4-3=4.5(x-2)?
