Do elimination
2x + y = 3
x - y = 3
Add these
3x = 6
X = 2
Plug in 2 for x
4(2) + 2y = 6
8 + 2y = 6
2y = -2
X = 2, y = -1
Answer:
Step-by-step explanation:
The question is not properly structured. Here is the complete question.
For cones with radius 6 units, the equation V=12\pi h relates the height h of the cone, in units, and the volume V of the cone, in cubic units. Sketch a graph of this equation on the axes.
The formula for calculating the volume of a cone is expressed as shown;
where r is the radius and h is the height.
Given radius r = 6units, on substituting;

It can be seen from the derived volume of the cone that it is linear in nature. The volume of the cone has a linear relationship with its height. As the volume increases, the height also increases and vice versa.
Generally for a direct variation

where k is the constant of proportionality. comparing to equation 1, k = 12π.
Find the graph attached
You need to use the slope intercept form. Also try M-A-T-H-W-A-Y
When finding x, you need to balance the equation.
To balance the equation, you need to do the inverse to the other side to get x all by itself.
x+69(-69)= 79(-69)
x= 10
I hope this helps!
