Here is a system of equations: 3x - y = 17
x + 4y = 10

a. Solve the system by graphing the equations (by hand or using technology).

b. Explain how you could tell, without graphing, that there is only one solution to
the system.

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "
