On a number line, a number, b, is located the same distance from 0 as another number, a, but in the opposite directior The number b varies directly with the number a. For example b
22 whena=-2Which equation represents this
direct variation between a and b?
Ob=-a
Ob--a
Ob-a=0
O b-a) =0

b=-a

Step-by-step explanation:

Becaude when b is positive a will be negative

And when b is negative a will be positive.

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 "

step-by-step explanation:

their are no angles. sorry cant .
