Answer:
1. -4x + 35 = - 1
2. x = 9 hours
Step-by-step explanation:
Starting at 1:00 pm, temperature changes - 4 degrees Fahrenheit per hour.
At 1:00 pm --> 35 degrees
Our equation will be y = -4x + 35
Substitute -1 in for y:
-4x + 35 = - 1 <--- Answer for the first question
-4x = -36
x = 9 hours <--- Answer for the second question
It will take 9 hours to reach -1 degrees Fahrenheit.
Hope this helps!
