3. which value of a below solves the equation: 3a +1=-a+3?
(1) -6
(2) 8
(3) -1
(4) s

None,

a=1/2

Step-by-step explanation:

Lets group together 'a' terms in one side of equations and lone terms on the other.

To do this, simply sum 'a' to both sides of equation, and also, subtract -1 (lone term).

3a+a=3-1

this leads to

4a=2

Where we obtain a=1/2

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
