Answer:
Difference between high and low temperatures: 12°F
Average change in temperature per hour: 2°F
Step-by-step explanation:
The difference between high and low temperatures was: 7 - (-5) = 12 (°F)
Midnight is 12am, so 6pm to midnight is 6 hours.
The average change in temperature per hour is: 12 / 6 = 2 (°F)
Answer:
given us,
slope= 0
(x1y1)= (3,-3)
here
(y-y1) =m(x-x1)
or, (y+3)=0(x-3)
or (y+3)= x-3
or, x+y= -3-3
x+y= -6
Step-by-step explanation:
x+y= -6
Answer:
constant of proportionality, k is 3
Step-by-step explanation:
constant, k= y/x
k=9/3
= 3
Answer: x=5
Step-by-step explanation:
Substitute 17 for n(x)
17=2x+7
Subtract 7 from both sides
10=2x
Divide each side by 2 to get the x by itself
x=5
