Step-by-step explanation:
Remember that if
= Identity Matrix
then
.
Also remember that for any invertible matrix
Identity Matrix.
Therefore

Therefore

The 2nd option is the answer :)!
Answer:
26
Step-by-step explanation:
Plug in 15 for y in the first problem so instead of y=x-11 it would be 15=x-11
15=x-11
+11= +11 (you want to add 11 to both sides to get x by its self)
26=x
The common difference of the sequence is -3 and the fifth term is 5
<h3>How to determine the common difference?</h3>
The sequence is given as:
17, 14, 11, 8....
The common difference is
d = T2 - T1
So, we have
d = 14 - 17
Evaluate
d = -3
Hence, the common difference of the sequence is -3
<h3>How to determine the
fifth term?</h3>
The fifth term is calculated as:
T5 = a + 4d
Where
a = T1 = 17
d = -3
So, we have:
T5 = 17 - 4 * 3
Evaluate
T5 = 5
Hence, the fifth term is 5
<h3>How to determine the
nth term?</h3>
The nth term is calculated as:
Tn = a + (n - 1)d
Hence, the nth term is Tn = a + (n - 1)d
