4 0

Answer:

The length of AB is \sqrt{74}\ units

Step-by-step explanation:

we know that

The formula to calculate the distance between two points is equal to

d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}

A(2,-6)\\B(7,1)  

substitute

d=\sqrt{(1+6)^{2}+(7-2)^{2}}

d=\sqrt{(7)^{2}+(5)^{2}}

d=\sqrt{49+25}

AB=\sqrt{74}\ units

Suppose a 5x8 coefficient matrix for a system has pivot columns. Is the system​ consistent? Why and Why not?
Lyrx [107]

Step-by-step explanation:

All the 5 rows of the coefficient matrix (since it is of order 5×8) will have a pivot position. The augmented matrix obtained by adding a last column of constant terms to the 8 columns of the coefficient matrix will have nine columns and will not have a row of the form [0 0 0 0 0 0 0 0 1]. So the system is consistent.
