Suppose that the monthly cost of a long-distance phone plan (in dollars) is a linear function of the total calling time (in minutes). When graphed, the function gives a line with a slope of 0.9. See the figure below. The monthly cost for 37 minutes of calls is $14.23. What is the monthly cost for 43 minutes of calls?

Anumber cube is rolled and a coin is tossed. the number cube and the coin are fair. what is the probability that the number rolled is less than 4 and the coin toss is tails?

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

Which steps could be part of the process in algebraically solving the system of equations, y+5x=x^2+10 and y=4x-10
