Both sides are the same so they are equal so...
4x+13=5x-15
x=28
If it took t hours to travel to college then it took 7-t to return home.
The distance travelled is the same so 15t=6(7-t), 15t=42-6t, 21t=42, t=2 hours.
So travel to college took 2 hours and it took 5 hours to return home.
The graph has the following key features:
(1) it shows the checking balance as a function of time (ie., at a given week)
(2) the graph is linear, showing a linear relationship between the balance and time. This is because the amount deposited is the same every week.
(3) the slope of the line is 134.12, since Terrance deposits $134.12 every week. The graph's y axis has different scale which makes the graph appear to have a slope close to 1, but, nevertheless, the linear function has slope of 134.12.
(4) the y-intercept is at 207.43 because at time 0 (week 0) there was a starting balance of $207.43
(5) The function in slope intercept form:
y = 134.12*x + 207.43
Let me know if you have questions.
Answer:
13.9
Step-by-step explanation:
To find the mean, add the two numbers and divide by two.
(13.9+13.9)/2=13.9
