Describe in words the region of double-struck r3 represented by the inequality. 0 ≤ z ≤ 7 the inequality 0 ≤ z ≤ 7 represents all points the planes z = 0 (the -plane) and z = 7.

All points between z = 0 and z = 7 along the z-azis in R3 x-y-z plane

Step-by-step explanation:

The inequality 1 z  7 represents all sets of points on the z-axis in the R3 plane that lies bewteen z = 0 and z= 7.

It is represents a line segment joining two point z= 0 and z=7 along z- axis in the R3 plane, while x=0 and y=0 on the x-y plane.
