Answer:
<h2>D. 9</h2>Step-by-step explanation:
We are given equation of total campsite charge
where
C is total campsite charge C (in dollars)
d is the number of days that the site is rented
so, here we will have
C is y-axis or dependent variable
d is x-axis or independent variable
we can find any two points and then we locate it
after that we can join them to get our graph
At d=0:
so, our point is (0,8)
At C=0:
so, our point is
now, we can locate these points and then join it
That’s the answer

Step-by-step explanation:
See attachment.
If both cyclists travel for the same time and speed, they will have travelled the same distance. Since one is headed north and the other east, we can see that the distance between them in one hour is the hypotenuse of a right triangle. Each leg has distance x. We can say x^2 + x^2 = (3)^2
2x^2 =1 8
x^2 = 9
x = 3
They both rode 3 miles.
