I'll work on the first one soon....
Uhhhh idk there is no information to be received to answer this question.Comment and post a pic.
sorry :(
Sorry don’t know. I’ll try to figure this out for you though!
Let X cones need to be sold for break even
Total cost of 12 cones =24
selling price for x cones = $2.5x
for break even 2.5x=24
That is x =24/2.5=9.6 cones (10 cones)
I hope this help
F(-10) means the x value in the equation is -10.
Replace x with -10 and solve:
4(-10) -12 = -40 - 12 = -52
F(-10) = -52
