Step-by-step explanation:
1/2(4-14y)=y+50
1/(8 - 28y) = y + 50
8y - 400 - 28y² +
Now you can solve
Answer:
12 °F
2°F per hour
Step-by-step explanation:
The difference can be found by substracting:
7°F-( -5 °F)
=12 °F
To find the average change in temperature per hour, divide by how many hours between 6 to midnight. Between 6 to midnight is 6 hours.
12°F / 6 hours
= 2°F/ hour
Answer: m= 1/420
Step-by-step explanation:
5x + 6y - 6y - 425x = 42
5x -425x = 42
0 = -420x - 42
m = -420
slope of a perpendicular line = 1/420
if that helps.
I think the answer is 9.375 if it needs to be in decimal form. If it needs to be in fraction form it would be improper, 9 3/8 would be the fraction. Hope it helps!
