A negative number raised to a certain power is equal to an undefined value. In this case, the goal of the have x equal to -k and numbers greater than it. Hence the domain includes k and numbers to infinity. The minimum value of the range is negative infinity up to a value where the first term is zero or range equal to c.Hence the answer is B. The domain is [-k,∞) & the range is (-∞,c].
Sure,I do not agree because the answer is -20>-27
16 × 35 = 560
560 + 960 = 1,520
1,520 / 19 = 80
80 / 16 = 5
Answer = 5
Hope this helped☺☺
I’m pretty sure This rounds to 900

Answer:
400 minutes
Step-by-step explanation:
The cost of the first plan is ...
A = 14 + 0.15m . . . . . . . . where m is the number of minutes used
The cost of the second plan is ...
B = 30 + 0.11m
The costs will be equal when ...
14 +0.15m = 30 +0.11m
0.04m = 16 . . . . . . . . . . . . . subtract 14+0.11m from both sides
m = 400 . . . . . . . . . . . . . . . divide by 0.04
The plans will have the same cost for 400 minutes of calls.
