R + d = 1750
r = d + 450
d + 450 + d = 1750
2d + 450 = 1750
2d = 1750 - 450
2d = 1300
d = 1300/2
d = 650 <=== what Dustin pays
r = d + 450
r = 650 + 450
r = 1100 ...Robert pays 1100
Answer:

Step-by-step explanation:
Equation of a circle:
The equation of a circle with center
is given by:

In which r is the radius.
Center (-14, -3)
This means that 
So



Passes through the point (-5,3),
This means that when
. We use this to find the radius squared. So



So, the equation of the circle is:


Yes, Aaron is 5'3. He is tall enough to ride the roller coaster.
The answer is 1 because you have to Substitute Two form X then it would just be Then substitute 2 form 1 and you would get 1
