two submersibles, one red and one blue, started rising toward the surface at the same time. they each rose at a constant speed. the red submersible starts rising from an altitude of 80 meters below the surface. after 30 seconds, it was 60 meters below the surface. the following equation gives the altitude (in meters relative to the surface) of the blue submersible as a function of time (in seconds). a= -90 + 0.6t

which submersible started rising from a higher altitude?

which submersible rose faster?

Before simplifying, how many terms are there in the expression 2x - 5y + 3 + x?

Since opening night, attendance at play a has increased steadily, while attendance at play b first rose and then fell. equations modeling the daily attendance y at each play are shown below, where x is the number of days since opening night. on what day(s) was the attendance the same at both plays? what was the attendance? play a: y = 8x + 191 play b: y = -x^2 + 26x + 126 a. the attendance was never the same at both plays. b. the attendance was the same on day 5. the attendance was 231 at both plays on that day. c. the attendance was the same on day 13. the attendance was 295 at both plays on that day. d. the attendance was the same on days 5 and 13. the attendance at both plays on those days was 231 and 295 respectively.
