Which situation can be represented by this equation? 6+0.5 X equals 26

The swimming pool is open when the high temperature is higher than 20∘c. lainey tried to swim on monday and thursday (which was 3 days later). the pool was open on monday, but it was closed on thursday. the high temperature was 30∘c on monday, but decreased at a constant rate in the next 3 days. write an inequality to determine the rate of temperature decrease in degrees celsius per day, d, from monday to thursday.

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