Answer:
There are 2 terms in 9x+3
One is 9x and another is 3
As having 2 terms it is known as binomial .
Let
X=<span>the original price of the pair of headphones
then
if the % </span>off sale is 40--------------- > (1-0.40)*X=<span>$36
x=36/0.60=60
the answer is
</span>the original price of the pair of headphones was $60
If a linear system has more unknown equations then it must have infinitely many solutions, which is true.
<h3>What is a linear equation?</h3>
A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
If there is only one equation with more than one parameter, then the number of the solution will be infinite.
If a linear system has more unknown equations then it must have infinitely many solutions, which is true.

Given :
A number
.
To Find :
What is the sum of 12 1/4 and it’s additive inverse .
Solution :
Fist we should know what is additive inverse .
Additive inverse of a number is that number , when added to it yield zero ,
Basically , for a real number , it reverses its sign :
The opposite to a positive is negative .
The opposite to a negative is positive .
Therefore , the sum of
and it's additive inverse is 0 .
Hence , this is the required solution .
