Step-by-step explanation:
we know that
The volume of a cone is equal to

In this problem we have

substitute the values


I got a $5000 scholarship. I spent $300 on a Nintendo Switch. How much money do I have now?
Y = 4+3x
2x+1 = y
Rewrite as two systems of equations.
3x - y = -4
2x - y = -1
Now use the substitution method to find the point of intersection.
You can also graph both equations on the same xy-plane using your graphing calculator to find the desired point.
