We can do the elimination method to find the solution for this problem. The elimination method involves adding the two equations together to get rid of a like term.
x + 2y = 7
+ x - 2y = -1
—————————
2x = 6
Now that we eliminated 2y because they cancel out, we are left with 2x = 6. Divide both sides by 2 in order to get x.
The answer is: x = 3.
Now that we know the numerical value of x, all we have to do is plug x into either system of equation in order to find the numerical value of y.
x + 2y = 7
3 + 2y = 7
2y = 4
y = 2
The solution to the problem is (3, 2).
Answer:
Similarities: both have a base which extends into a single vertex.
Differences: a cone only has 1 edge and a pyramid has a minimum of 6 (for a triangular pyramid).
the base of a pyramid is a polygon - the base of a cone is a curve
(a mathematical cone has no edges at all it is a continuous sheet - or two sheets if you consider the vertex as dividing the surface into two sheets).
