Below are the supply and demand equations for umbrellas in a certain market. In these equations, p represents price, D represents demand, and S represents supply. D = StartFraction negative 4 over 3 EndFraction p 22 S = 3 p minus 36 What is p at the point of equilibrium, to the nearest tenth? a. 19. 3 b. 16. 5 c. 13. 4 d. 12. 0.

What is the value of  y  in the solution to the system of equations? x  +  y  =  12x  –  3y  =  –30a. –8b. –3c. 3d. 8

An equation where variables are used to represent known values—function notation true or false

Determine the number of outcomes in the event. decide whether the event is a simple event or not. upper a computer is used to select randomly a number between 1 and 9 comma inclusive. event upper b is selecting a number greater than 4. event upper b has nothing outcome(s). is the event a simple event? (yes or no) because event upper b has (fewer than, exactly, more than) one outcome.
