Answer:
We know that our number m is more than -(7 2/3)
Then we must write this as:
m > -(7 2/3)
At most -10 is written as:
m ≤ - 10.
Then the statement:
"A number m is more than -7 2/3 or at most -10" is written as:
m > -(7 2/3) ∨ m ≤ - 10.
Where ∨ means "or".
The graph of this will look like:
A white dot in the point -(7 2/3) and a line that goes to the right. And a black dot at -10, and a line from that that goes to the left.
Remember that white dot means that the element is not a solution, and that is used for the symbols > <
And a black dot means that the element is a solution, is used for the symbols ≤ ≥
