Step-by-step explanation:
The solution is where both graph cross each other.
Is the solution, the point (x, y) that they gave you, the same point as where the two graph cross each other?
If yes then the solution is correct.
If no then the solution is wrong.
This may not be the best explanation but hopefully at the very least it'll guide you!
When you multiply or divide a negative by another negative, you get a positive. When it is a negative and a positive, it remains negative.
Assuming your question simplified into a equation (or number form? Been a while, haha!) is 32÷-2÷(-16÷4), it would end as a positive. Because you first divide the positive 32 by a negative 2, you get a negative. Because -16÷4 is in parenthesis, it is done because following the rest of the equation (P.E.M.D.A.S.!), it would be 32÷-2÷-4. Going from left to right, as you should, it results in a negative being divided by another negative, so you get a positive. 32÷-2÷(-16÷4) = 32÷-2÷-4 = -16÷-4 = 2!
Answer:
The equation of the circular wheel is
.
Step-by-step explanation:
Given :
Radius of Ferris wheel r = 70 feet.
The distance between the wheel and the ground = 4 feet.
Also, the rectangular coordinate system shown has its origin on the ground directly below the center of the wheel.
So the x coordinate of center of wheel must be 0 , and y coordinate = 70 + 4 = 74
Thus, Coordinates of center = (0,74)
The equation of circle is given by :-

Now center (h,k) = (0,74) and r = 70 , we get

Hence, the equation of the circular wheel is
.
B (sorry if wrong) hope this helps
