Answer:
you are correct
Step-by-step explanation:
p.s the way you worded this was confusing
Try graphing the 3 first (you know it's positive 3 because it has a + before it, and you know the line is going to go down (negative) because it has a - before it, after that you can find the slope if the line, in this case 1/2, and move one unit down (because it's negative) and 2 to the right
Hope this helped! :)
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!
