Answer:
x=-9
Step-by-step explanation:
1. 7-3x=34
2. Subtract 7 from both sides to get -3x=27
3. Divide by -3 from both sides to get x by itself which turns out to be x=-9, for 27÷(-3)=-9
It is equal to 9.461 x 10 km

4 quadrant because on a graph a + and + are 1 then a - and a + are 2 then a - and a - are 3
Answer:
the matrix described in the question is a linearly independent matrix, and linearly dependent matrix has a unique solution. <em>see further explanation below</em>
Step-by-step explanation:
For any matrix to have a pivot column in all its column, it means that the matrix must be linearly dependent
Thus, as the columns are linearly independent , the system of equation have a unique solutions
.
