Answer: D) Inverse does not exist
<u>Step-by-step explanation:</u>
The top row is 0 0 , which makes the determinant equal to zero.
The reciprocal of 0 is undefined so there cannot be an inverse for this matrix.
Answer:
(x - 4)(x + 4)(x - 1)(x + 1)
Step-by-step explanation:
Given
- 17x² + 16
Use the substitution u = x², then
u² - 17u + 16
Consider the factors of the constant term (+ 16) which sum to give the coefficient of the u- term (- 17)
The factors are - 16 and - 1, then
u² - 17u + 16
= (u - 16)(u - 1) ← replace u by x²
= (x² - 16)(x² - 1) ← both factors are difference of squares
= (x - 4)(x + 4)(x - 1)(x + 1)
The answer is x=5 x= -3
I plugged and checked and trust me the both work
For the first picture, the answer is the third option. for the second picture, the answer is the first option. hope this helps!
Answer:
5< 23
Step-by-step explanation:
we know that
A mathematical expression of five is 5
A mathematical expression of less is <
A mathematical expression of twenty-three is 23
therefore
"Five is less than twenty-three" is equal to
5< 23
