Answer:
Option B
Step-by-step explanation:
Since, number of calories 'C' burned is proportional to the number of minutes (m) given to the exercise,
C ∝ m
C = km
Where k is the proportionality constant.
From the table attached,
For C = 250 calories and m = 30 minutes,
250 = 30k
k = 
= 
Therefore, equation representing this situation will be,
C = 
Option B will be the correct option.
Answer:
x^3-8x^2-5x+84
Step-by-step explanation:
The polynomial can be found by expanding (x+3)(x-4)(x-7)=x^3-8x^2-5x+84
Answer:
x ≥ 767
The number of bags sold must be greater than or equal to 767 to make a minimum profit of $6900.
Step-by-step explanation:
If they want a profit of at least $6900, then the total amount earned would have to be ≥ 6900. You can always earn more than $6900, but the lowest should be equal to $6900.
So if we use x as the number of bags sold, and we know that each bag will earn $9, then x • 9 ≥ 6900.
If we divide both sides by 9, then the number of bags sold must be ≥ 767.
