Step-by-step explanation:
1/3(6+3)
= 1/3(9)
= 3

Explanation:
This is a self-answering question: you solve it by graphing the equations.
<em>The solution is where the lines intersect</em>. The point of intersection of the lines is the point that satisfies all the equations for the lines, hence is a solution to the system. If they do not intersect, there are no solutions. If the lines are coincident, there are an infinite number of solutions.

The equations can be graphed by any of a number of methods. (My favorite is to let a graphing calculator do it.) The method of choice depends on the coefficients and the form the equations are given in. Methods of graphing are a topic for a more lengthy discussion.
Answer:
4
Step-by-step explanation:
6+10=16
2+2=4
16/4 = 4
Answer:
Length = 40
Height = 20
Step-by-step explanation:
If you multiply 40 x 20, it equals 800
20 is also half of 40 as well.
Answer:
<em>Functions:</em>
3. The chart with arrows
4. The graph
<em>Not Functions:</em>
1. (1,1), (2,2), (3,3), (1,4)
2. (1,17), (0,16), (0,15), (-2,17)
Step-by-step explanation:
Functions do not have repeating domains (x-coordinates).
Hope it helps!
