Use cramer's rule to determine if the system is inconsistent system or contains dependent equations. 2x + 7 = 8 6x + 3y = 24 que
Natali [406]
Answer: In the equations that you have given, we have a dependent system.

2x + y = 8 (I assumed that you meant to type y instead of 7)
6x + 3y = 24


To use Cramer's Rule, we have to take the determinant of 3 different matrices written in the problem. Taking the determinant of the coefficient matrix produces a zero.

2  1   This is the coefficient matrix.
6  3

6 - 6 = 0

Since this is 0, the rest of the work will be undefined meaning the systems are dependent (or they are the versions of the same equation).

How many different twotwo​-letter passwords can be formed from the letters
Anna [14]

Answer:

70

Step-by-step explanation:

GIVEN: two two​-letter passwords can be formed from the letters  A, B, C, D, E, F, G and H.

TO FIND: How many different two two​-letter passwords can be formed if no repetition of letters is​ allowed.

SOLUTION:

Total number of different letters =8

for two two​-letter passwords 4 different are required.

Number of ways of selecting 4 different letters from 8 letters=^8C_4

                                                                                                   =\frac{8!}{4!4!}

                                                                                                  =70

Hence there are 70 different two-letter passwords can be formed using 8 letters.
