As a fundraiser, a school club is selling posters. the printer charges a $23 set-up fee, plus $0.75 for each poster. then the cost y in dollars to print x posters is given by the linear equation y=0.75x+23. the printing of 50 posters cost $60.50. the printing of 100 posters costs $98.00. find the number of posters x if the printer billed the club for the costs of $173.00.

Which value of m will create a system of parallel lines with no solution? y = mx - 6 8x - 4y = 12

The function below is written in vertex form or intercept form. rewrite them in standard form and show your work. y = -3(x-2)(x-4)

Naruto is choosing between two venues that will deliver food to his house. with probability 1/3 he will choose ramen mania (r), and with probability 2/3 he will choose sushi (s). if he chooses r, 15 minutes after making the call, the remaining time it takes the food to arrive is exponentially distributed with average 10 minutes. if he orders s, 10 minutes after making the call, the time it takes the food to arrive is exponentially distributed with an average of 12 minutes. given that he has already waited 25 minutes after calling, and the food has not arrived, what is the probability that he ordered from r? i am really stuck on how to set this up, so if you could be extra clear, that would be super ! in advance
