Answer:
(2) Molecules of I2 are polar, and molecules of Br2 are nonpolar.
(3) Molecules of Br2 have stronger intermolecular forces than molecules of I2.
(4) Molecules of I2 have stronger intermolecular forces than molecules of Br2.
None
Explanation:
The system of equation that represents this situation is y = 20x + 15 for day and night kernel and y = 30x + 5 for bark time hotel.
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change and b is the initial value of y.
Let y represent the total charges for for boarding a pet in x days.
Day and night kennel charges $20 per day plus a one-time food fee of $15 to board a pet. Hence:
y = 20x + 15
Bark time hotel charges $30 per day plus a one-time food fee of $5. Hence:
y = 30x + 5
The system of equation that represents this situation is y = 20x + 15 for day and night kernel and y = 30x + 5 for bark time hotel.
