You are right, it's C. I checked in geogebra bro/girly/dude.
Hope this helps !

<span>Note D = r(t)
20min = 1/3 hr and 10min = 1/6 hr
(1/3hr)30mph + (1/6hr)3mph = 10.5 mi, the total distance traveled.
total distance / total time = average speed = 10.5/(1/3 + 1/6) = 10.5/(2/6 + 1/6)
10.5mi/.5hr = 21mph
Hope This Helps

The total number of students take speech at rocky valley college is 4806
Average means the "central" value of a set of numbers. To calculate it: add up all the numbers, then divide by how many numbers there are.
Given
Number of students in the rocky valley college = 14418
Student who take speech = 1/3
So, the total number of students who took part in speech is
=> 14418 x 1/3
=> 14418/3
=> 4806

You can isolate y on both sides, getting:
2x-17=y and x-10=y
Then, make the two y equal each other, and solve the equation
2x-17=x-10
The answer would be x=7.
then, plut in the amount into one of the equations:
x-y=10
7-y=10
y=-3
T
Therefore, the answer is x=7 and y = -3, or (7,-3)
You graph it by the y axis and that have a number 1 and you graph it straight sideway
