It took him 7 minutes to run each mile.
Firstly, covert the time into minutes.
3 * 60 = 180 minutes
180 + 2 = 182 minutes
Now in order to find how long he ran each mile,
divide 182 by 26
182/26 = 7 minutes
Answer:
Step-by-step explanation:
Undefined.
1) + $12, since it is a profit
2) -1440 ft, since it is below the sea level
3) - 22°F, since it is below
4) + 31 yards, since it is a gain.
In slope-intercept form, we have these values (y = mx + b):
m = slope
b = y-intercept
Change the equation from standard form to slope-intercept form.
-9x + 7y = 28
-9x + 9x + 7y = 28 + 9x
7y = 28 + 9x
7y/7 = 28/7 + 9x/7
y = 4 + 9/7x
y = 9/7x + 4
Therefore, the y-intercept is 4.
Best of Luck!
