Plug the point and the slope into point-slope form and simplify to get it in slope-intercept form.
Where y1 is the y-value of the point, x1 is the x-value, and 'm' is the slope.
Distribute 1/2:
Add 4 to both sides:
or
The answer is 83, using the equation of 320-79-81-77=x and X is equal to 83
Answer:
7.5 hours
Step-by-step explanation:
We can model an equation for this problem.
We can write:
Where
F is the final temperature (15 degrees we need)
m is the rate of temperature change (2 degrees per hour)
and
t is the time, in hours, it will take (we need to find this)
It is given,
F = 15
m = 2
So, t would be:
F = mt
15 = 2t
t = 15/2 = 7.5
So it will take 7.5 hours
I think 45 because if you look at the top of the other 45 the graphs look the same lengths except this one stretches out so 45°
Answer:
150 people
Step-by-step explanation:
First, look over the chart and find the rows that have listed as 26 - 30 and 31 - 35.
Find out how high the row goes by looking at the number on the side of the gram.
26 - 30 goes to 60
31 - 35 goes to 90
Then add the 2 numbers together and you will find your total
60 + 90 = 150 people
