Answer:
y = 
Step-by-step explanation:
multiply
by
to get
:
+ y -
= 
simplify:
y +
= 
subract
from both sides:
y = 
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
The temperature at 5 am was -3 degrees
12-15=-3
Answer:
(x,2) > (2,x)
Step-by-step explanation:
y=x
(x,y) > (y,x)
Ok so nevermind i won't help
