Answer:
C. Yes, because A does not have a pivot position in every row.
Step-by-step explanation:
The pivot position in the matrix is determined by entries in non zero rows. The pivot position may be in the row or a column. By Invertible Matrix Theorem the equation Axequalsb has non trivial solution. A has fewer pivot positions therefore A is not invertible. Ax will map RSuperscript into real numbers for n times. A has pivot position if left parenthesis bold x right parenthesis.
Answer : 16
Given f(x) table is
x –5 –2 1 5
f(x) –11 1 13 29
Given g(x) table is
x -5 –2 1 5
g(x) –7 –1 5 13
We need to find the value of (f-g)(5)
(f - g) (5) = f (5) - g(5)
We know f(5) = 29 and g(5) = 13 from the table
(f - g) (5) = f (5) - g(5) = 29 - 13 = 16
the value of (f – g)(5) is 16

Step-by-step explanation:
Answer:
x=31
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
We take a look at this expression:
and notice that both terms are square numbers.
and
.
There is a specific formula that I highly recommend you memorize involving differences of squares. It states that given the difference of squares
, it can always be factored into
.
Here, we can apply that. In this case, a = 7x and b = 3. So:

Thus, the answer is A.
Hope this helps!
