Answer:
<h2>"A number subtracted from 3"</h2>Step-by-step explanation:
The given expression is
Notice that this expression is about a difference between a variable and the number 3.
Remember that a variable is called "a number" in a general form, indicating that it's an unknown value.
So, the best way to state the meaning of this expression is
"The difference between a number and 3" or
"A number minus 3" or
"Three subtracted from a number".
Now, a wrong way to represent this expression is
"A number subtracted from 3", this is wrong because it's indicating the difference in the wrong direction, this statement is setting the number as negative, which is not true.
Therefore, the right answer is
<h3>"A number subtracted from 3"</h3>I graphed this line below.
Start with an open dot on 7.
The reason we use an open dot is because x
does not equal 7, it is only greater than 7.
So from your open dot, draw an arrow to the right
to represent all numbers greater than 7.
Finally, state your answer in set notation if possible.
It is read as {x: x > 7}.
