Answer:
Add the equations in order to solve the first variable. Plug this value into the other equation in order to solve the remaining variables.
The point form is (3,-1)
The equation form is x = 3, y = -1
Hope this helps!

Answer:
x = - 
Step-by-step explanation:
Given
20x + 12 = 4x - 16 ( subtract 4x from both sides )
16x + 12 = - 16 ( subtract 12 from both sides )
16x = - 28 ( divide both sides by 16 )
x =
= -
[ = - 1.75 ]
Direct variation mean x =ky so y = x/k
(2,14) mean y = kx so 14 = k*2 so 14 = 7*2 so 14 = 14
(4,28) mean y = kx so 28 = k*4 so 28 = 7*4 so 28 = 28
from these result that the 3rd choice is right sure
The surface area of the cone is: A. 184π units².
<h3>What is the Surface Area of a Cone?</h3>
Surface area of a cone = πr(l + r), where r is the radius and l is the slant height.
Given the following:
- Slant height (l) = 15 units
- Radius = (r) = 8 units
Surface area of a cone = π8(15 + 8)
Surface area of a cone = 184π units²
