Answer:

To do this, you imagine a vertical (up and down) line moving across your graph from left to right. It should only be touching the line at one point at a time. If it is touching more than one point on the line at a time, the line is not a valid function. The first line and its inverse both pass the test.

One number exceeds another by 44. the sum of the numbers is 24. what are the numbers?

baherus [9]

Let, the numbers = x,y

x+y= 24 1st eqn

x-y = 44 2nd eqn

24-y-y = 44

-2y = 44-24

y = 20/-2 = -10

substitute that in equation 1st x = 24+10 = 34

so, the numbers would be 34 & -10

Answer: The answer is in the attached figure.

Step-by-step explanation: We are given to draw a net for a rectangular prism of length 8 units, width 2 units and height 3 units.

What is a rectangular prism? It is a a solid three-dimensional object consisting of six faces, where each of the face is a rectangle. The same cross-section along a length of a rectangular prism makes it a prism. We also call it as a cuboid.

As given in the question, a rectangular prism ABCDEFGH is drawn in the attached figure, where length is 8 units, width is 2 units and height is 3 units.
