f (x) = { 19 + 0.39(x - 300), x > 300
Step-by-step explanation:
Andrew has a cell phone plan that provides 300 free minutes each month for a flat rate of $19. For any minutes over 300, Andrew is charged $0.39 per minute. Let x be the number of minutes Andrew uses per month and f(x) be the charges based on Andrew's cell phone plan.

Given: x + y = 15. Which of the following are ordered pairs of this equation? {(-3, 14),(0, 15),(3, 16)} {(-3, 16),(0, 15),(3, 1
xenn [34]
Ordered pairs for this equation would be (0,15) and (15,0)
F=EA(e/l)
e/l=EA/F
l=Fe/EA
