Let y be the temperature
Let m be the rate of temperature drop in degrees per hour
Let x be the number of hours elapsed since 8PM
The initial temperature (at x = 0) is 0
y = mx
Four hours from 8 PM, the temperature was -16.8 degrees
-16.8 = m(4)
m = -4.2 degrees per hour
At 9PM, one hour will have elapsed.
y = -4.2(1)
y = -4.2 degrees
172, since he bought two boxes and each had 516 there was 1,032 in all. Since he wants them to last 6 months, then you divide by six and get 172 :) I think this is what it is asking.
The value of X must be 0. Hope this helps and a Brainliest would be appreciated
1!!!!!!!!!!!!!¡¡!one because 5/5 = 1
2nd and 3rd option looks correct. 1st option is not true and I am pretty sure 4th one is not true as well
