Answer:
7,-7 are the solutions
Step-by-step explanation:
Not a perfect square so its
+-7
I would go with -7 since its the lowest amount
F varies directly with m ⇒ f/m =k ( this k remain the same )
when f=-19 and m=14 ⇒ k=f/m= - 19/14
when m=2 , f/m= - 19/14
f/2= -19/14
f= -2*19/14=-38/14= (-38:2)/(14:2) = - 19/7
⇒ f= -19/7

Answer: 4420 cals
Explaining:
221 every half hour
To find every hour you times it by 2 which equals to 442
1 hour = 442
2 hours = 442 times 2
2 hours= 884
To find how much a week you times it by 5
884 times 5
Equals to 4420 cals a week
