Answer:
460 minutes, or 7 hours and 20 minutes.
Step-by-step explanation:
Your formula is 0.14x+23=0.19x
X represents your minutes.
0.14*460+23=87.4
0.19*460=87.4
That would be f(x) = 4|x|. Reason is, the bigger the number that's multiplied by |x|, the narrower the graph will be. The opposite is true for the smaller the number, & so f(x) = .5|x| will be wider.
Hope this helps!
