For this case we have:
Let x be the variable that belongs to the real numbers. Then, all reals less than 70 can be expressed as:
The tip of the inequality is directed to the real numbers, since they tell us that they are less than 70, for 70 the inequality remains open.
Answer:
I'll go out on a limb and suppose you're given the matrix
and you're asked to find the determinant of
, where
and given that
.
There are two properties of the determinant that come into play here:
(1) Whenever a single row/column is scaled by a constant
, then the determinant of the matrix is scaled by that same constant;
(2) Adding/subtracting rows does not change the value of the determinant.
Taken together, we have that
