Hello,
y=5+x
y=x²-7
==>x²-7=5+x
==>x²-x-12=0
==>(x-4)(x+3)=0
The points are:
(4,9) and (-3,2)
The volume of cone is double of the volume of cylinder.
Further explanation:
We have to find both volumes first to compare the volumes of both.
Volume of Cylinder:
Given
Diameter = d = 8 inches

Height of cylinder=h=3 inches

Volume of Cone:
Radius=r=4 inches
Height of cone= h= 18 inches

We can see that

The volume of cone is double of the volume of cylinder.

Answer:
1. 8x + 2y = 16
Step-by-step explanation:
3x - 12y = 10
12y = 3x - 10
y = 1/4 x - 5/6 .... slope: 1/4
perpendicular line slope: -4
8x + 2y= 16
2y = -8x + 16
y = -4x + 8 .... slope: -4
