At S400 per person, an airline anticipates selling 250 tickets for a particular flight. At 8500 per person, the airline anticipates selling 150 tickets for the same flight. Assume a linear relation between the cost per ticket C and the number of tickets, z sold. Which of the following equations can be used to model the given information?
C =-1x+655
C =-. +655

How many solutions does the nonlinear system of equations graphed bellow have?

With this question substitute t=3 and t=5 to determine if the two expressions are equivalent. 4(t + 3) 4t+12 which statements are true? check all that apply. a. the value of both expressions when t =5 is 32. b. the two expressions are not equivalent. c. the value of both expressions when t=3 is 15. d. the value of both expressions when t=5 is 23. e. the two expressions are equivalent. f. the value of both expressions when t=3 is 24.

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
